  • And not just any dinosaurs, but two-legged carnivorous, feathered 'theropods' like the 30-inch-tall Bambiraptor -- somewhat less cuddly than its namesake. (
  • Although the vast majority of feather discoveries have been in coelurosaurian theropods, feather-like integument has also been discovered in at least three ornithischians, suggesting that feathers may have been present on the last common ancestor of the Ornithoscelida, a dinosaur group including both theropods and ornithischians. (
  • Further comparisons of bird and dinosaur skeletons, as well as cladistic analysis strengthened the case for the link, particularly for a branch of theropods called maniraptors. (
  • While they are theropods relatively closely related to the raptors therizinosauroid dinosaurs are also very different, having long necks, huge claws on their hands, and perhaps a herbivorous diet. (
  • Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers . (
  • Theropods are bipedal, mostly carnivorous dinosaurs. (
  • In recent years, scientists have discovered that feathering was present on many extinct theropods, but only on those that are classified as coelurosaurs, a diverse group including T. rex and birds. (
  • Because the new species sits deep within the evolutionary tree of theropods, the findings suggest that all predatory dinosaurs might have had feathers. (
  • Rather than Archaeopteryx, paleontologists have come to believe birds evolved from a group of dinosaurs called theropods from the Early Cretaceous period of Earth's history, around 120 million to 130 million years ago. (
  • Most feathered dinosaurs have been in a class known as theropods. (
  • That immediately means that probably half or more of the non-avian theropods had feathers of some kind or another covering at least part of their bodies. (
  • Currently however, there's no direct evidence for any feathers in the basal theropods. (
  • These are the nearest relatives to the theropods and there's no evidence for feathers or filaments of any kind for any of this group. (
  • Richard Hinchliffe of the University College of Wales also examined evidence relating to the tridactyl hand, which is composed of digits 1-2-3 in dinosaurs, the most critical characteristic linking birds to derived theropods. (
  • Palaeontologists have known for decades that theropods, the dinosaur group that contained the likes of Tyrannosaurus and Velociraptor and from which modern birds evolved, were covered in feathery structures. (
  • This finding builds on a long history of work trying to understand how birds and dinosaurs are related, helped by a spate of recent discoveries of "missing links" - bipedal, carnivorous dinosaurs (or theropods ), exhibiting quintessentially avian features, such as wishbones and feathers. (
  • One of the clinchers was the discovery of theropods with feathers, preserved exquisitely in fine volcanic ash in China . (
  • As a result, the bipedal carnivorous theropods must be closely related to birds, with both groups acquiring their plumage from a common feathered ancestor . (
  • The presence of feathers in some of the oldest and most primitive theropods - such as Sinosauropteryx - indicates feathers appeared very early in theropod evolution. (
  • As a result, feathers should have characterised all advanced theropods, including gigantic forms such as Tyrannosaurus rex . (
  • The vast majority of feather discoveries have been for coelurosaurian theropods . (
  • In 2017, Baron, Norman, and Barrett proposed that feathers or featherlike structures may have originated with the common ancestor of the Ornithoscelida , a group of dinosaurs which includes both theropods and ornithischians , the only two dinosaurian clades in which feathers have been observed so far. (
  • The new fossils have provided clues for reinterpreting older fossils, too: we can now see where complex feathers attached (or "inserted") on the arm bones of theropods, the carnivorous bipedal dinosaurs that include T. rex and the velociraptors. (
  • This gives more weight to a very well-supported theory that modern birds evolved from Theropods, the group of small carnivorous dinosaurs to which Sinosauropteryx belonged. (
  • Inferences from other sources, not from the amber, were brought into the interpretation, even though the discoverers admitted, "There is currently no way to refer the feathers in amber with certainty to either birds or the rare small theropods from the area. (
  • There is currently no way to refer the feathers in amber with certainty to either birds or the rare small theropods from the area . (
  • The dancing dinos were likely two-legged carnivorous dinosaurs known as theropods, according to research project leader Martin Lockley and his team. (
  • A tiny, earlier cousin of Tyrannosaurus rex sported at least a partial coat of hairlike feathers, scientists reported today. (
  • Knowledge of the origin of feathers developed as new fossils were discovered throughout the 2000s and 2010s and as technology enabled scientists to study fossils more closely. (
  • And among these filaments, a team of Chinese and British scientists have found the distinctive signs of melanosomes, small structures that are partly responsible for the colours of modern bird feathers. (
  • Scientists have recently discovered a new bohaiornithid bird specimen from the Early Cretaceous Period of China with remarkably preserved feathers. (
  • A team of Chinese, American and Belgian scientists have unearthed a 161-million-year-old dinosaur fossil showing that the animal may have had vibrant, iridescent plumage like that of peacocks and other birds today. (
  • The scientists think that C. juji sported iridescent feathers on its head as well as in its wings and tail, probably putting them to use as a type of sexual display, to show off to potential mates. (
  • January 24, 2012-Scientists have determined the color of a fossilized feather of Archaeopteryx , a birdlike dinosaur that represents an evolutionary transition between dinosaurs and today's birds. (
  • Conversely, some creation scientists with expertise in other disciplines remain unconvinced that those secular descriptions have eliminated enough evolutionary bias to legitimize feathered dinosaurs as a Genesis-friendly category. (
  • While a large majority of secular scientists agree that some dinosaurs had feathers, creation scientists remain divided. (
  • 2 Since secularists could more easily construe a feathered dinosaur to fit that third category, biblical scientists should show healthy caution in interpreting feathered dinosaur claims. (
  • The weakest of two arguments from authority that we have encountered in friendly verbal discussions asserts that creation researchers should trust evolutionary scientists' labels of 'feathered dinosaurs' because the evolutionists have first-hand and thus the most intimate knowledge of the fossils. (
  • Now, scientists describe more feathers in amber found near that same 2016 find. (
  • Scientists know when Anchiornis roamed the Earth, it was nearly completely covered in feathers and had four wings - one on each limb. (
  • Dinosaurs may have sported more feathers than scientists originally thought, and some are even debating whether most if not all had feathers. (
  • Fossils of a tiny bird-like dinosaur from China has been discovered by scientists, that sport flashy rainbow feathers and a bony crest on its snout that it used to attract mates. (
  • The genes that caused scales to become feathers in the early ancestors of birds have been found by US scientists. (
  • Oregon State University scientists have released a new study debunking the alleged evolution of dinosaurs into birds. (
  • WASHINGTON - An exquisite fossil of a fierce little Chinese dinosaur dubbed the "dancing dragon" that lived 120 million years ago - an older cousin of the Velociraptor - is showing scientists that feathers grew differently on dinosaurs than on birds. (
  • Scientists are eager to understand the plumage differences between birds and these feathered dinosaurs. (
  • Analysis of the calamus would have allowed scientists to ascertain the source of the feather on the animal from which it came. (
  • Scientists know that birds evolved from dinosaurs, and Archaeopteryx is part of that evolutionary path. (
  • In a report on Thursday in the journal Nature, the scientists said the 125 million-year-old dinosaur, excavated in China, was covered with distinct feathers that had a familiar, modern look. (
  • Scientists suspect that feathers evolved for some purpose other than flight, perhaps for warmth, and only later, and with other physical changes, were they cleared for takeoff. (
  • The Dinosaur Feather" takes readers deep into the insular world of scientists, centered at the University of Copenhagen, who are investigating dinosaur evolution, particularly the question of how birds descended from dinosaurs. (
  • Scientists never expected to find plumage on a dinosaur as large as Yutyrannus , because, at least in mammals, larger-sized animals retain heat more efficiently than small animals. (
  • According to Dr Paddy Orr, UCD School of Geological Sciences , University College Dublin, one of the scientists involved in the research, "melanosomes are colour-bearing organelles buried within the structure of feathers and hair in modern birds and mammals, giving black, grey, and rufous tones such as orange and brown. (
  • But in a new Nature study , a team of British and Chinese scientists report that they found a way to unlock the color patters of one of the earliest feathery dinosaurs -it had a red mohawk, they say, with a red and white striped tail. (
  • Once upon a time, scientists believed that it would be impossible to find anything other than the hardened fossilized remains of extinct dinosaurs. (
  • And if those dinosaurs really were millions of years old, those scientists would have been 100% correct. (
  • Today, artist-scientists are ahead of both the public and the museums in visualizing the "new" dinosaurs. (
  • by Chinese scientists, there is evidence to suggest that Theropod dinosaur species at different growth stages may have had dramatically different feathers. (
  • A team of scientists from China and the United Kingdom have published a paper indicating that some small Theropod dinosaurs were red heads, in fact, sort of ginger coloured all over. (
  • The melanosomes contain the pigment melanin and from the ratio of different shaped melanosome structures found in the fossilised feathers the scientists have concluded that this particular Sinosauropteryx was ginger coloured. (
  • The scientists have also discovered that this diminutive carnivore had a "Mohican" of feathers running along its head and back and a striped tail. (
  • The most noticeable update to the T. rex we all know and fear is its feathers, which scientists now believe stretched from the crown of its head down along its neck and back like a horse's mane. (
  • Feathers are rare in the fossil record-the conditions have to be just right for softer parts like feathers or hair to survive normal decay-and scientists have never unearthed evidence of an actual T. rex feather. (
  • Scientists think the glossy plumes of the Microraptor may have helped the small, meat-eating dinosaur signal its good health and suitability as a mate to others, much the way fancy colours serve birds of our era. (
  • Armed with more data than before about the creature's physical characteristics, and new ways to uncover the colours of feathers with scanning electron microscopes, scientists set about to uncover its hues. (
  • Unrelated to my previous post , news came today from the journal Nature that a group of scientists have used SEM techniques to reveal color patterns from some well preserved dinosaur feathers -- cool stuff! (
  • In an attempt to study ancient lives and habitats, scientists in China and America has found that Anchiornis, one of the earliest feathered dinosaurs, could to fly like birds due to the lack of certain kind of proteins in its feathers. (
  • Since the discovery of feathers in dinosaur fossils nearly 20 years ago, it has become something of an article of faith among some scientists that many, if not all, dinosaurs sported some fluff - either in the form of plumage or feather-like structures called protofeathers. (
  • In analyzing the catalog of dinosaur skin fossils and impressions, the scientists found that some traits were shared among almost all known dinosaurs, including scales and bony plates. (
  • Using a new laser imaging technique to reveal traces of soft tissue in fossils of an early feathered, birdlike dinosaur, scientists have found direct evidence of a wing structure needed for flight that was previously invisible from the preserved bone evidence. (
  • Newfound fossils of a feathered dinosaur suggest that the extinct reptiles might have possessed a diversity in plumage types that puts modern birds to shame. (
  • But birds completely change the types of feathers in their coats just once their entire lives: when they switch from warm down to their adult plumage. (
  • Seeing fuzzy Deinonychus or some other dromeosaur with a splash of plumage never looked quite right and I didn't understand why in the course of a few years predatory dinosaurs went from being scaly to being covered in down. (
  • It is entirely possible that even the terrifying Tyrannosaurus had plumage during at least some stage of its life, perhaps to regulate body temperature when small but shedding the feathers as it quickly became larger, and even the recently described Jurassic tyrannosauroid Guanlong (Xu et al 2006) may have had feathers. (
  • Many groups view these filaments as proto-feathers, the evolutionary predecessors to the fine plumage of birds. (
  • The fossil, which is of a baby Sciurumimus and just about 28 inches long, was found in the limestones of northern Bavaria and preserves remains of a filamentous plumage, indicating that the whole body was covered with feathers. (
  • A patch of three oddly short feathers spotted among the fossilized plumage of Microraptor may be the first evidence of a nonbird dinosaur molting. (
  • An odd gap (arrow) in the plumage on the right forelimb of this Microraptor fossil was created by molting, with three new feathers coming in (colored in the inset as green, yellow and orange), researchers say. (
  • A new study of fossilized bird feathers from 100 million years ago has determined that the broad stripes visible on the feathers do indicate the color of that ancient bird's plumage. (
  • Study coauthor Derek Briggs says the next step is to investigate the structure of fossilized feathers from an ancient bird thought to be closely related to a living bird with varied and colourful plumage. (
  • K]nowing the colour of dinosaur plumage could reveal something about their daily lives and ecology, [coauthor Jakob] Vinther says. (
  • Yet Yutyrannus demonstrates that the loss of plumage is not necessarily a consequence of large size in dinosaurs. (
  • Some gigantic maniraptoran dinosaurs (or "raptors," a sister group to tyrannosaurs which includes extant bird species) are assumed to have possessed feathers, but direct evidence of plumage has never been found. (
  • All three known individuals of Yutyrannus also possessed an impressive plumage of long fine feathers, some over 20cm long. (
  • A team of researchers from the Institute of Vertebrate Palaeontology and Palaeoanthropology (IVPP) from Beijing have interpreted the fossils and produced a paper suggesting that unlike modern birds, the plumage and feathers of dinosaurs changed as these animals grew and reached maturity. (
  • Dinosaurs have been found with some sort of fluff or even full-on plumage. (
  • A feather-covered herbivorous dinosaur offers a surprising perspective on plumage. (
  • He compared the skeletal structure of Compsognathus, a small theropod dinosaur, and the "first bird" Archaeopteryx lithographica (both of which were found in the Upper Jurassic Bavarian limestone of Solnhofen). (
  • He showed that, apart from its hands and feathers, Archaeopteryx was quite similar to Compsognathus. (
  • The leading dinosaur expert of the time, Richard Owen, disagreed, claiming Archaeopteryx as the first bird outside dinosaur lineage. (
  • The notion that birds and dinosaurs are closely related has been around for a very long time, kicked off by the discovery of Archaeopteryx and Compsognathus in the mid-19th century and popularized by T.H. Huxley. (
  • Archaeopteryx was considered to be a bird, too derived to be comfortably called a feathered dinosaur, and while it became increasingly important as a transitional fossil a transition from what was debated. (
  • Eventually the morphological problems that faced the dinosaur hypothesis, like the supposed absence of clavicles, were overcome with new evidence and increased study but more than Archaeopteryx was needed to confirm the predictions being made. (
  • The alleged first bird Archaeopteryx had the classic avian through-flow lungs , while the alleged feathered dino Sinosauropteryx had a clearly reptilian bellows lung . (
  • It had a huge fan tail, similar to that of Archaeopteryx , its more famous feathered cousin. (
  • von Meyer proposed the feather be named Archaeopteryx lithographica . (
  • The closeness of the timing and location caused the two finds to be linked together, with the feather considered the singular piece of evidence - the holotype - of a bird-like dinosaur to be called Archaeopteryx . (
  • In the years since the 1860s, other specimens of feathered dinosaurs have been found, including 11 or 12 specimens of Archaeopteryx , notably one residing in a Berlin museum. (
  • While the newly identified primary covert somewhat resembles the Berlin specimen's secondary feathering - its closest match among all existing Archaeopteryx specimens - they're clearly not the same. (
  • While it could be that the fossil is of an Archaeopteryx feather not yet catalogued, the greater likelihood is that it belonged to some other, thus far undiscovered feathered dinosaur. (
  • Researchers have been studying Archaeopteryx fossils for 150 years, but new X-ray data reveal that the bird-like dinosaur may have been an "active flyer. (
  • CNN) - For more than 150 years, researchers have been studying the fossils of bird-like dinosaur Archaeopteryx and attempting to answer this question: Did it fly? (
  • Archaeopteryx is not a direct ancestor to modern birds but rather a member of a larger group of elaborately feathered dinosaurs that appears to have engaged in a variety of experimental modes of dinosaurian flight,' Voeten said. (
  • The Chinese discoverers reported finding all stages of feather evolution and ancestral birds, even though the deposits are at least 25 million years younger than those containing the earliest known bird Archaeopteryx. (
  • It appears that many early birds, such as Archaeopteryx , may also have had long feathers on their hind limbs. (
  • A recent study of an Archaeopteryx feather demonstrated it was black. (
  • Those on the tail show a frond-like arrangement just like the iconic early long-tailed bird Archaeopteryx , suggesting this was a relatively common feature in early birds and closely related bird-like dinosaurs. (

  • Evolutionary biologists have been piecing together the details for nearly 40 years, and this month, a major prediction about feather evolution has been vindicated. (
  • With this fossil discovery, all major stages of feather evolution predicted by evolutionary biologists have been found in the fossil record. (
  • Whatever their function, it is clear that feather evolution is yet one more example of a major theme in evolutionary biology: structures that have one function today frequently began their evolutionary history serving a very different function. (
  • At the very least, probably a few more did too (since the odds on us finding the very first ones to get feathers are pretty tiny) and some fairly weak evidence suggests that feather may have appeared rather earlier in evolutionary terms, suggesting a few more theropod groups had them too. (
  • The idea of an evolutionary link between dinosaurs and birds has changed from a view. (
  • We therefore suggest that feathers first arose as agents for colour display and only later in their evolutionary history did they become useful for flight and insulation. (
  • Feathers are key to the success of birds and we can now dissect their evolutionary history in detail and see how each feather type - and the fine detail of feather structure - was acquired through time. (

  • Birds of today are blessed with feathers that are composed primarily of flexible beta-keratins and at certain time during the evolution of feathers, one of the beta-keratin genes was deleted, making the protein slightly smaller, according to the researchers. (
  • And, the gene deletion, according to the researchers, happened around 145 million years ago, millions of years later than Anchiornis lived, so this kind of feathered dinosaurs had no shortened protein form to give them functional flight feathers. (

  • Specimens like "Dave" (a probable Sinornithosaurus , Ji et al 2001, the first specimen of Sinornithosaurus millenii also bearing filamentous feathers [Xu et al 1999]) threw greater weight to the notion that birds had evolved from predatory dinosaurs. (

  • According to Science Magazine, there is increasing evidence that feathers were common in carnivorous dinosaurs and may have developed earlier than previously thought. (
  • The dinosaur is also interesting, because it is a member of the compsognathid group, which branched off from the family tree of carnivorous dinosaurs fairly early in the history of the group, Martill says. (
  • That suggests that the use of feathers for complex display purposes may have a very ancient history within the carnivorous dinosaurs. (
  • These extinct feathers would not have been useful for warmth, for example, given how flat they are, Xu said. (
  • After all, most of the fossils with bona fide feathers were definitely birds, and the questionable ones could also represent some strange, extinct, bird kinds. (
  • For nearly two centuries, people have struggled to imagine what the great extinct dinosaurs looked like. (
  • In 2008 Vinther and colleagues published a paper in Biology Letters describing the find, in which they proposed, 'The discovery of preserved melanosomes opens up the possibility of interpreting the color of extinct birds and other dinosaurs. (
  • A new species of feathered dinosaur has been discovered, and its gigantic size makes it the largest-known feathered animal, living or extinct. (
  • Amazingly we do know the colours of some other dinosaurs and extinct birds. (
  • Among extinct dinosaurs, feathers or feather-like integument have been discovered on dozens of genera via both direct and indirect fossil evidence. (

  • Birds and extinct non-avian dinosaurs share many unique skeletal traits. (
  • His study shows that melanosomes have been preserved in the same way in the filaments of Sinosauropteryx as they were in the true feathers of early birds. (
  • Under the extreme magnification of an electron microscope, Zhang looked at the filaments of the dinosaurs Sinosauropteryx and Sinornithosaurus , as well as the true feathers of the early bird Confuciusornis . (
  • Sinosauropteryx is the first fossil dinosaur to have its color scientifically established. (
  • One of the animals analyzed, the Sinosauropteryx , a small, meat-eating dinosaur, appears to have had alternating bands of dark and light along its tail. (
  • The research found that the theropod dinosaur Sinosauropteryx had simple bristles - precursors of feathers - in alternate orange and white rings down its tail, and that the early bird Confuciusornis had patches of white, black and orange-brown colouring. (
  • Furthermore, we now know that the simplest feathers in dinosaurs such as Sinosauropteryx were only present over limited parts of its body - for example, as a crest down the midline of the back and round the tail - and so they would have had only a limited function in thermoregulation. (
  • A number of small, feathered Theropod dinosaurs are known from the area, dinosaurs such as Sinosauropteryx and Sinornithosaurus as well as birds, plant remains and even insects. (
  • Similicaudiptery was not known to be a flying dinosaur and Persons contends its tail feathers evolved as a means of waving its feathered tail fans. (
  • Based on dissections of modern reptile and bird tails, Persons reconstruction of the dinosaur's tail muscles revealed oviraptors had what it took to really shake their tail feathers. (
  • Large muscles extended far down the tail and had a sufficient number of broad connection points to the vertebrae to propel oviraptor's tail feathers vigorously from side to side and up and down. (
  • The tail feathers are asymmetrical but wing feathers are not, a bizarre feature previously unknown among dinosaurs including birds," said Xu. (
  • This suggests that controlling flight might have first evolved with tail feathers during some kind of aerial locomotion," he said. (
  • These tail feathers were around 30 per cent of the length of the skeleton, making them the longest known feathers of any (non-bird) dinosaur. (
  • Yutyrannus tail feathers. (
  • Dr. Michael Pittman said the importance of the discovery is that Jianianhualong tengi possessed asymmetrical feathers, a feature commonly associated with flight - the tail feathers of Jianianhualong tengi are asymmetrically vanned - one side of the feather is wider than the other - just like in living birds and the 'four-winged' gliding dromaeosaurid Microraptor (lived around 120 million years ago). (
  • Microscopic barbules on tail feathers in the specimen. (
  • That's because modern birds and their closest Cretaceous ancestors have fused tail vertebrae, or pygostyles, that enable tail feathers to move as a single unit. (
  • The wing and tail feathers of the more mature dinosaur resemble quill pens. (
  • The early juvenile also has smaller wing feathers than tail feathers, but this size difference is less significant in the specimen that represents an older more mature specimen. (
  • Nonetheless, the feather claim has its defenders as well, such as Prof. Zhang Fucheng of the Chinese Academy of Sciences and his colleagues, who claim to be "refuting recent claims that the filaments are partially decayed dermal collagen fibres. (
  • The fossils of some small meat-eating dinosaurs were covered in filaments that are widely thought to be the precursors of feathers. (
  • Their presence in dinosaur filaments has allowed Fucheng Zhang to start piecing together the colours of these animals, millions of years after their extinction. (
  • For a start, they appear inside the feathers and filaments, rather than sitting outside them in a thin film. (
  • Dinosaur fossils sometimes show fibrous filaments, but these are hardly feathers. (
  • Dissenting evolutionists (those who do not believe dinosaurs evolved into birds) at the Florida symposium showed how those filaments looked just like decaying skin fibers from partly rotten carcasses. (

  • The fossil of a chicken-sized, meat eater from Brazil that had a mane of fluffy filaments and a pair of stiff, ribbon-like streamers emerging from both shoulders is the first dinosaur with feathers ever discovered in the Southern Hemisphere. (
  • After studying feathers with a known color pattern, he found that the dark-pigment particles appeared only where the black bands did-and in the fossils they aligned perfectly with the individual feather filaments, an unlikely arrangement for bacteria. (
  • A cast of a specimen of Psittacosaurus , a horned dinosaur, preserved with 'filaments' along the top of the tail. (
  • However, two species have turned up that have feather-like filaments on their bodies. (
  • Not dinosaurs themselves, but close relatives, and many pterosaurs are known to have been covered in fur-like filaments called pycnofibers . (
  • Its long arms and legs each had sets of feathers that looked similar to those on bird wings, while most of the rest of its body was covered by fluffy filaments. (
  • I'd go so far as to say that all dinosaurs had some sort of genetic trait that made it easy for their skin to sprout filaments, quills and even feathers. (
  • These filaments are morphologically similar to the protofeathers that have been found as compression fossils associated with some dinosaur skeletons. (
  • The fossil showed a perfectly preserved small, Theropod dinosaur with a covering of an enigmatic fuzz ("protofeathers"), some of these feathery filaments were up to 4cm long. (
  • They found single filaments (stage I in the model), tufts (stage II), simple feathers (stage III), barbed feathers (stage IV), and advanced veined feathers (stage V) suitable for flight or for diving (as found in grebes). (
  • Species like Caudipteryx and the four-winged Microraptor had true feathers with asymmetric vanes arranged around a central shaft. (
  • New fossil analyses of Microraptor , a nonbird feathered dinosaur that lived about 120 million years ago, reveal its molting behavior - and suggest the dinosaur was a frequent flyer. (
  • Microraptor 's shorter feathers appear in just a small patch on one of the dinosaur's four wings - suggesting that the dinosaur molted sequentially, too, bird ecologist Yosef Kiat at the University of Haifa in Israel and colleagues report. (
  • These small dinosaurs - such as Microraptor , Anchiornis and Xiaotingia - had large flight feathers on their hind limbs as well as their fore limbs, and they had long bony tails, similarly replete with large feathers. (
  • Microraptor was the first of the four-winged dinosaurs to be discovered, in 2003, and it was tiny for a dinosaur: approximately 1kg in weight and similar to a crow or a raven in size. (
  • Do you really think that it's likely the feathers of Microraptor gui's holotype are bird feathers that happened to be placed in exactly the right place to have perfect wings with primaries, secondaries and coverts, similar arrangements on the legs, and retrices on the distal tail? (
  • What possible evidence could you have for these being non-Microraptor feathers? (
  • The feathers on Microraptor gui's holotype (IVPP V13352) the four-winged dinosaur as you call it) ARE part of the original fossil. (
  • There's been a lot of speculation about how the feathers of Microraptor were oriented and whether they formed airfoils for flight or whether they had to do with sexual display," he adds. (
  • So while we've nailed down what colour this animal was, even more importantly, we've determined that Microraptor , like many modern birds, most likely used its ornate feathering to give visual social signals. (
  • There are even very small dinosaurs, such as Microraptor and Anchiornis , which have long, vaned , arm and leg feathers forming wings. (
  • His student Gregory S. Paul depicted non-avian maniraptoran dinosaurs with feathers and protofeathers, starting in the late 1970s. (
  • The team identified fossilized melanosomes-pigment-bearing organelles-in the feathers and filament-like 'protofeathers' of fossil birds and dinosaurs from northeastern China. (
  • The Smithsonian's Sues added, 'I think that one can safely say that this find invalidates some recent attempts to deny the existence of protofeathers in birdlike dinosaurs by claiming (without compelling evidence) that they are degraded collagen fibers. (
  • The very concept of feathered dinosaurs arose only a few decades ago, when new fossils from China began to reveal fossilized fibres and later actual feathers still associated with some dinosaur-like fossils, plus fossilized fibres interpreted as protofeathers on other fossils. (
  • Theagarten Lingham-Soliar of the University of KwaZulu-Natal in South Africa examined the skin of modern reptiles, the effects of decomposition on skin, and the fossil evidence relating to alleged feather progenitors (protofeathers). (
  • Feduccia, Lingham-Soliar and Hinchliffe found no evidence for the existence of protofeathers on dinosaurs and no evidence in support of the morphogenesis of the feather from putative filamentous protofeathers. (
  • They suggest that 'protofeathers' described on fossil findings "are probably the remains of collagenous fiber 'meshworks' that reinforced the dinosaur integument. (
  • I am purposely avoiding the use of both "feathers" and "protofeathers" in this post as both of these are loaded terms. (
  • What's really needed now is some detailed work on the structure and chemistry of the more equivocal skin features, like quills and some 'protofeathers,' to see how much they really resemble feathers or not," Barrett said. (
  • A new species of feathered dinosaur discovered in southern Germany is further changing the perception of how predatory dinosaurs looked. (
  • That God, what a cheeky fellow - putting down fake dinosaur bones and fake dinosaur feathers! (
  • Because unlike most dinosaur fossils, which are nothing but mineralized bones, this creature was well enough preserved that one could analyze the shape of some of its internal organs. (
  • The artwork and text are attractive and interesting, and readers will learn how dinosaur bones became fossils and how their remains were eventually discovered. (
  • If a number of species in a lineage are known to have feathers, and if they also have some nice correlate (like quill knobs on the bones that indicate feathers) then that's pretty convincing that the rest of the group had them too. (
  • Nearly 100-million-year-old wing tip features bones, soft tissue, and feathers preserved in amber. (
  • While the other dinosaurs have bird-like, triangular skulls and long forearm bones in comparison to birds today, Caihong had a long and narrow skull, and unlike many of these other dinosaurs, its short forelimbs show proportions more akin to modern birds. (
  • Dinosaur fossils are mostly drab collections of mineralized bones. (

  • White fibers from a Late Cretaceous dinosaur Shuvuuia deserti stained positive for β-keratin antibodies in a 1999 paper, followed by many similar immunological claims for Mesozoic protein in bones and integument. (
  • However, in 2004 Mark Norell, curator of paleontology and the new T. Rex exhibit at AMNH, and his colleagues in China discovered the imprint of ancient, hair-like feathers pressed into the rock alongside the bones of an early tyrannosaur species, Dilong paradoxus . (
  • [2] Fossil evidence also demonstrates that birds and dinosaurs shared features such as hollow, pneumatized bones , gastroliths in the digestive system, nest-building and brooding behaviors . (
  • However, Heilmann noted that birds had clavicles (collar bones) fused to form a bone called the furcula ("wishbone"), and while clavicles were known in more primitive reptiles, they had not yet been recognized in dinosaurs. (
  • The research is part of a body of work on the cutting edge of paleontology, leveraging new technology to flesh out the study of fossils beyond bones, to look at soft tissue and feathers. (
  • Extrapolating from primitive pigment-giving organelles known as melanosomes (which contain the coloring compound melanin and are still prevalent in modern animals) that have been found in fossilized dinosaur feathers from the Cretaceous period, a research team paints a picture of dark wings and brightly striped reddish tails.

  • It also demonstrates that the unique assemblage of characters that make a modern bird - feathers, wings, lightweight skeleton, enhanced metabolic system, enlarged brain and visual systems - evolved step-by-step over some 50 million years of dinosaur evolution, through the Jurassic and Cretaceous periods. (
  • Middle Jurassic to Early Cretaceous deposits from northeastern China have yielded varied theropod dinosaurs bearing feathers. (

  • Norell, a curator and chair of the division of paleontology at New York's American Museum of Natural History, said the discovery supports theories that dinosaurs were birdlike, warm-blooded creatures that evolved feathers to stay warm not to fly. (
  • Some early observers thought Oviraptor was birdlike, but the "sluggish lizard" paradigm about dinosaurs was so established that physical evidence such as feather insertion points were overlooked for years. (
  • Theropod dinosaurs, thought to be the direct ancestors of birds, sported birdlike feathers. (
  • This view began to shift during the so-called dinosaur renaissance in scientific research in the late 1960s, and by the mid-1990s significant evidence had emerged that dinosaurs were much more closely related to birds, which descended directly from the theropod group of dinosaurs and are themselves a subgroup within the Dinosauria. (
  • For example, caenagnathids are a family of theropod dinosaurs and part of a group of dinosaurs most evolutionists think are most similar to birds. (
  • It's a theropod, like Tyrannosaurus rex , but more specifically it's a member of Paraves - a group of dinosaurs whose members include the lineage that gave rise to birds. (
  • As he notes, the last vertebrae in the tails of the group of dinosaurs known as oviraptors "were fused together forming a ridged, blade-like structure. (
  • In fact, birds are now believed to have descended directly from the theropod group of dinosaurs, [3] and are thus classified as dinosaurs themselves, meaning that any modern bird can in cladistic terms be considered a feathered dinosaur. (
  • Recent discoveries point to the possibility that a great many, maybe even most, non-avian dinosaurs had feathers or something similar as part of their body covering. (
  • Other recent fossil discoveries have included signs of fuzz and down on such ancient creatures, but the new find was described as unmistakable evidence of early feathers in dinosaurs that did not fly. (
  • These discoveries confirm the substantial body of evidence that suggests birds evolved through a long line of theropod (flesh-eating) dinosaurs. (
  • These discoveries open up a whole new area of research", said Professor Benton, "allowing us to explore aspects of the life and behaviour of dinosaurs and early birds that lived over 100 million years ago. (
  • Indications of feathers have been found on much older fossils, and the new discoveries indicate feathers continued to develop into modern form before the extinction of dinosaurs, explained Norell, who was not part of the research team. (

  • Caihong juji , the fossil of which was first found by a farmer in northeastern China, was roughly the size of a duck and covered in feathers. (
  • It had asymmetrical feathers in part of the tail - which is surprising, because such asymmetrical feathers are used for flying and thus are typically found in the wings. (
  • Those crests are found on much older dinosaur species, and haven't been seen on younger species with "true" feathers. (
  • The fossilized remains found in northeastern China suggest Eosinopteryx, while feathered, was a flightless dinosaur with a small wingspan and a bone structure that would have restricted its ability to flap its wings. (

(
  • From their careful examination of the available evidence they offer an interim attempt to define morphologically the most salient features of Aves: "Birds are mesotarsal bipedal archosaurs with pennaceous feathers, and a tridactyl avian hand composed of digits 2-3-4. (

  • As I have written here recently, the actual number of non-avian dinosaurs that truly preserve feathers is pretty low (just a few of dozen or so at most) compared to the number of species out there, but still more than one might expect given their general rarity. (
  • Before now, Beipiaosaurus was the largest-known non-avian feathered dinosaur, and it was a huggable turkey-sized mass just two meters or so long. (
  • Many birds, the living descendants of non-avian dinosaurs, use brightly colored tails for courtship displays. (
  • These new insights show that even small dinosaur groups can experience this phenomenon, helping us to understand how these animals and their avian cousins evolved. (

  • [1] Moreover, fossils of more than thirty species of non-avian dinosaur have been collected with preserved feathers. (
  • Previous analyses have suggested that the dinosaur didn't just glide from tree to tree, but was able to launch itself from the ground using its wings and back legs ( SN: 10/28/16 ). (
  • First off, one part of an animal might be scaly and another feathered (think chicken feet vs wings). (
  • However, unlike birds today, Caihong's asymmetrical feathers were on its tail, not its wings - a finding that suggests that early birds may have had a different steering or flight style. (
  • IN THE EARLY stages of evolving flight, feathered dinosaurs tried an interesting experiment: they developed four wings. (
  • These transitional forms have cemented the view that birds are nothing more than a strange but very successful lineage of dinosaurs that developed feathers, wings and powered flight. (
  • God engineered exquisite flight feathers for lightweight aerodynamic efficiency. (
  • They argue that the long flight feathers on Changyuraptor 's tail were an adaptation that allowed this relatively large animal to land without fear of crashing into the ground, which becomes more of a problem for large flying animals. (
  • And not just hairy kiwi-style feathers, but complex, asymmetrical vaned ones, like the flight feathers of modern birds. (
  • This baby dinosaur has bizarre flight feathers, which are strikingly different from those of adults. (
  • As I learned more, however, I came around to the notion that any Deinonychus or Velociraptor that appears without feathers is a naked dinosaur, a growing body of evidence showing that there were probably many more feathered dinosaurs than had previously been suspected. (
  • One of the most prominent recent claims is that birds evolved from theropod dinosaurs, a supposedly carnivorous group that included T. Rex and Velociraptor . (
  • The fossil animal was identified as a dromaeosaur, a fast-running two-legged dinosaur related to Velociraptor. (
  • The absence of feathers on the juvenile specimen suggests that the feathers appeared only when the males were old enough to mate. (
  • So the best evidence of feathered dromaeosaurs does not come from the same quarry or even the same city as NGMC 91, and where exactly the 'Archaeoraptor' specimen is from is unknown (no precise locality data were taken by the collector before it was forged and sold). (

  • This means that this feature (asymmetrical feathers) evolved earlier than previously thought - at least 160 million years ago - because a common ancestor is always older than its descendant groups. (
  • This study makes important steps towards reconstructing the early evolution and function of asymmetrical feathers. (
  • Tyrannosaurids are predominantly large dinosaurs with short forelimbs that roamed Earth 130 to 65 million years ago. (

  • There is fossil evidence that other members of the tyrannosaur family had feathers. (
  • The fossil of Sciurumimus albersdoerferi, which lived about 150 million years ago, provides the first evidence of feathered theropod dinosaurs that are not closely related to birds. (
  • Despite evidence to the contrary, most evolutionists today still generally agree that dinosaurs had feathers. (
  • The long, filament-like feathers preserved with three relatively complete skeletons of the newly described species provide direct evidence of extensively feathered gigantic dinosaurs. (
  • its a large debate amongst paleontologist's whether or not dinosaurs were feathered, with some choosing to believe they were and others refuting the evidence as inconclusive, such as the apparent feathers simply being a tree branch or other anomaly, not feathers. (
  • They provide evidence that dinosaurs laid soft-shell eggs. (
  • But this is the first fossil evidence of a nonbird dinosaur exhibiting this behavior. (
  • Despite some uncertainty in the scientific community about embracing the idea of many dinosaurs sporting feathers, Godefroit believes the evidence from the extensive Russian find was conclusive. (
  • U of A Paleontology researcher Scott Persons followed a chain of fossil evidence that started with a peculiar fusing together of vertebrae at the tip of the tail of four different species of dinosaurs, some separated in time and evolution by 45 million years. (
  • Sp far, there hasn't been any direct fossil evidence of feathers in the species that followed Similicaudiptery , but there is a lot of other, strong evidence, that they possessed a feathered tail. (
  • In terms of evidence, as noted, feathers or anything like them (well, any kind of soft tissue really) are rarely preserved. (
  • Since dinosaurs first evolved in a world without flowering plants, a world dominated by greens and browns and since a substantial body of scientific evidence indicates that most dinosaurs had colour vision, then one can speculate that feathered dinosaurs may have been very colourful indeed. (
  • This view began to shift during the so-called dinosaur renaissance in scientific research in the late 1960s, and by the mid-1990s significant evidence had emerged that dinosaurs are much more closely related to birds . (
  • Before the discovery of feathered dinosaur fossils, the evidence was limited to Huxley and Ostrom's comparative anatomy . (
  • The truth is that this latest find is even more evidence that dinosaurs are far, far younger than we have traditionally been taught. (
  • That's all changing as fossil evidence shows how widespread feathers were among dinosaurs. (
  • This is further evidence that many dinosaurs were covered in downy feathers, perhaps to keep them warm but also for display. (
  • "This is the first time anyone has ever had evidence of original colour of feathers in dinosaurs," said Professor Benton. (
  • A brand-new dinosaur find from China is the best evidence yet that some dinosaurs had feathers . (
  • Some mainstream ornithologistsincluding Smithsonian Institution curator Storrs L. Olsondisputed the links, specifically citing the lack of fossil evidence for feathered dinosaurs. (
  • Although some reviewers have raised questions about the naming and interpretation of this fossil, if correct, this early Jurassic fossil is the oldest known evidence of feathers, almost 30 million years older than the next-oldest-known evidence. (
  • Studies conducted earlier claims that Anchiornis, a small, feathered, four-winged dinosaur that lived in China around 160 million years ago is strong evidence that dinosaurs transformed into birds. (
  • Birds evolved from small feathered dinosaurs roughly 150 million years ago. (
  • Palaeontologists report their findings of Galeamopus pabsti , a new sauropod, and Jianianhualong tengi , a small feathered dinosaur. (
  • Anchiornis dinosaurs are key to our understanding of the origins of birds, Pittman continued. (
  • Laser scans reveal a detailed outline of Anchiornis huxleyi, which paleoartists can use to reconstruct the dinosaur in a more accurate way. (
  • Building on previous techniques using ultraviolet light, Dr. Pittman and his colleagues shone a violet laser on fossils of Anchiornis, a winged dinosaur that lived 160 million years ago in the late Jurassic period, around the time birds evolved flight. (
  • Last year, Vinther reported that the layers of melanosomes in another fossil feather would have given it an iridescent sheen, much like the gloss on the wing of a starling. (
  • That year, Yale graduate student Jakob Vinther and colleagues, using a scanning electron microscope, discovered melanosomes in the dark bands of a hundred-million-year-old feather. (
  • These earlier findings proved it was possible for melanosomes from dinosaur times to survive in fossils. (
  • Because melanosomes are an integral part of the tough protein structure of the feather, they survive when a feather survives, even for hundreds of millions of years. (
  • Scanning electron microscopes have shown melanosomes to be present, indicating that these strange features were not the remains of collagen or connective tissue, but most probably feathers. (
  • Melanosomes are colour-bearing organelles buried within the structure of feathers and hair in modern birds and mammals, giving black, grey, and rufous tones such as orange and brown. (
  • the melanocytes migrate into the dermal pulp of the developing feather germ, where the melanin is packaged into melanosomes and then those melanosomes are transferred to keratinocytes for deposition into developing feathers. (
  • I wonder, if we hadn't figured out a while back that dinosaurs were feathered ancestors of birds, how we would have interpreted such a discovery. (
  • Alan Feduccia, about birds 'dated' younger than their alleged dinosaur ancestors. (
  • This means that feathers probably existed in the common ancestors of both lineages. (
  • This seemingly feathery nontheropod dinosaur shows that feathers were not unique to the ancestors of birds and may even have been quite widespread. (
  • A study of a new species of dinosaur discovered in Russia had feathers, and, added to other species discovered around the world since 1996, seems to indicate feathered dinosaurs may have been more common than previously considered, The New York Times said . (
  • describe an early neornithischian dinosaur with both early feathers and scales. (
  • One major point evolutionists use to support their 'missing link' between birds and dinos is dinosaurs having feathers. (
  • This statement flew in the face (so to speak) of a majority of evolutionists at the symposium who believed that heavy-tailed theropod dinosaurs somehow sprouted feathers and evolved into today's heavy-chested birds. (
  • 1 In the complete absence of genuine dinosaur feather examples, evolutionists supply hypothetical ones. (
  • 6 Two evolutionists later criticized the 2011 Science paper, saying that proposed protofeather fibers could actually be plant material or mammal hair and not even from dinosaurs. (
  • When Schweitzer originally made her discovery public, she was viciously attacked by other evolutionists who insisted that finding dinosaur soft tissue that was millions of years old was absolutely impossible. (
  • Much as I love all the new theories (new since my childhood anyway) about dinosaur coloring, and feathers, it mostly means that the kids' books I read to my son about dinosaurs feature animals who appear to be wearing fringed feather sleeves, in lurid colors, over a typical scaly dinosaur skin. (
  • By contrast, the ornithischian lineage - which had animals such as Triceratops, Stegosaurus and Ankylosaurus - and the huge, long-necked dinosaurs in the sauropod lineage, were considered to be scaly. (
  • Probably that means the common ancestor of all dinosaurs had feathers," Godefroit said. (
  • I think that the common ancestor of dinosaurs probably had feathers, and that all dinosaurs had some type of feather, just like all mammals have some type of hair. (
  • If feathers were not inherited from a common ancestor then they would have to evolve several times within the coelurosaurs, such large-scale convergence being unlikely. (
  • And all the descendants of this common ancestor potentially could have feathers as well. (
  • Birds and dinosaurs had a common ancestor way back further in time. (
  • we reconstructed these feathers at their closest common ancestor (the closest common ancestor of birds). (
  • Her extraordinary remains, unearthed in Montana, shed light on the evolution of egg-laying as well as on gender differences between this and other meat-eating dinosaur species. (
  • Some of the Ancient West's most distinctive and downright weird dinosaur species - from the famous Tyrannosaurus rex to the odd therizinosaurs - turn out to be members of an exclusive group: According to new research, they and others like them were the only true feathered dinosaurs. (
  • Since scientific research began on dinosaurs in the early 1800s, they were generally believed to be closely related to modern reptiles, such as lizards. (
  • Our feathered friends were beaten to the punch by the pterosaurs, a group of flying reptiles (related to dinosaurs) that filled the skies from 228 to 66 million years ago. (
  • We have great fossil sequences of horse evolution, camel evolution, human evolution, the transition from fish to tetrapods, dinosaurs to birds, reptiles to mammals, land animals to whales, and many others. (
  • In some cases, the fossil feathers are clearly striped by bands of pigment and the alleged eumelanosomes only turn up in the dark ones, just as you'd expect. (
  • It was no great stroke of luck that these pigment particles were still left in the fossilized feathers. (
  • Unfortunately, we don't yet know the colour of these impressive feathers, as the pigment cells were not reported. (
  • Pigment cells in feathers can be fossilised under optimal conditions, such as rapid burial under fine volcanic ash, and pigment cells of different colours have distinctive shapes and texture. (
  • By focusing on tiny elements of pigment in the fossil called melanomes and comparing them to those of modern birds, the team was able to tell that the dinosaur's feathers were black with a blue sheen. (
  • Most of the books I had seen didn't explain it beyond "These dinosaurs were closely related to birds," something I didn't dispute but was not enough to make me feel comfortable with feathered raptors. (
  • But a comprehensive new survey of the known fossils and impressions of dinosaur skin suggests that feathers were only characteristic of a particular group: two-legged meat-eaters that are most closely related to modern birds. (
  • But the ancient feathers are actually a type that has been lost in the course of evolution, and the role they played on the younger juvenile remains unknown. (
  • Illustrations and museum models of feathered dinosaurs are not based on fossils but only on evolution-inspired imagination. (
  • LiveScience cautioned, however, that "the fossil record of this evolution from simple to complex feathers is spotty. (
  • The fossil of the dazzling dinosaur, described in the journal Nature Communications, sheds fresh light on the evolution of these ancient animals and their relationship to birds. (
  • These 125-million year old fossils expand our knowledge of feather evolution. (
  • The findings also help to resolve a long-standing debate about the evolution and original function of feathers. (
  • fascinating and exciting discovery with important implications for understanding dinosaur evolution and biology. (
  • Their hypothesis: The evolution of feathers made dinosaurs more colorful, which in turn had a profoundly positive impact on communication, the selection of mates and on dinosaurs' procreation. (
  • Since he was a firm believer in Dollo's law , which states that evolution is not reversible, Heilmann could not accept that clavicles were lost in dinosaurs and re-evolved in birds. (
  • Measuring 25 feet (7.5 meters) from snout to tail, the species was covered in long filamentous feathers, as shown by the fossilized imprints around recovered skeletons. (
  • According to media reports, "nearly-complete skeletons" have been discovered that even include skin and feathers. (
  • Fossils include complete or nearly-complete skeletons associated with preserved soft tissues such as feathers, fur, skin or even, in some of the salamanders, external gills. (
  • Before, ideas of dinosaur anatomy came from looking at fossilized skeletons and drawing comparisons with related animals alive today such as birds and crocodilians. (
  • The findings suggest feathered dinosaurs might have undergone a flurry of changes as they matured-unlike anything seen in modern birds, said study co-author Xing Xu of the Chinese Academy of Sciences in Beijing. (
  • Modern birds continuously replace old feathers with new ones. (
  • The long quills on the older Similicaudipteryx are much like those seen on modern birds, and they might have served as ornaments or to help the dinosaur balance itself as it ran. (
  • Similicaudipteryx' s odd changes suggest that early birds and feathered dinosaurs experimented with a diversity of feather types and a variety of ways to use them, 'which only later stabilized to the more conservative system we see now with modern birds,' Xu said. (
  • At the same time, paleoartists began to create modern restorations of highly active dinosaurs. (
  • In modern-day birds, feathers develop at a very young age, shortly after hatching. (
  • That suggests, said the team, that the feathers were probably decorative for the purpose of attracting mates, much like those on a modern peacock. (
  • Beautiful fossils, mainly from China, show that several species of dinosaur had feathers akin to the flight-capable plumes of modern birds. (
  • But this illustrates why we are all quite familiar with modern dinosaurs. (
  • They resemble the "feather quill knobs" that we see in modern turkey vultures. (
  • The microscopic structure of its feathers resembles that of modern hummingbirds. (
  • Unlike many aquatic birds, modern songbirds lose only a few feathers at a time, enabling them to stay aloft year-round for foraging or to escape predators. (
  • All modern, adult birds molt at least once a year to replace old, damaged feathers, or to exchange their bright summer colors for drab winter camouflage. (
  • The folds of skin in front of the elbow and behind the wrist (called patagia) were covered in feathers, just like in modern living birds. (
  • New research is strongly supporting the theory that many species of dinosaurs used their feathers for sexual display, in a similar way to what modern peacocks do. (
  • Skin, muscle, claws, and feather shafts are visible, along with the remains of rows of feathers similar in arrangement and microstructure to modern birds. (
  • Aside from making Jurassic ecosystems of 161 million years ago more colourful, the dinosaur is interesting because it has features that are both ancient and modern. (
  • These modern-looking feathers show definitively that they evolved in dinosaurs before the emergence of birds and flight, and that therefore feathers are not an adaptation for flight," Norell said. (
  • Its feathers are almost identical structurally to those of modern birds. (
  • The long bony tail of Changyuraptor , and the foot-long feathers it sported, are unlike the short tails in modern birds," co-author Dr Alan Turner of New York's Stony Brook University told reporters. (
  • Psittacosaurus gobiensis , also known as the "parrot reptile of the Gobi," resembles a less beaky version of the modern-day macaw and is the first dinosaur suspected to feast on nuts and seeds. (
  • It also reveals that they were assuming that feathers first evolved on dinosaurs for "nonornamental functions" such as thermoregulation - yet many modern birds, like geese, also use some of their feathers (down feathers) for thermoregulation. (
  • They also have muscular control over their feathers, as modern birds do - so the spectacular and vivid feathers on its tail, for instance, can be fanned out as required. (
  • The folds of skin in front of the elbow and behind the wrist were covered in feathers, similar to modern birds. (
  • Feathers could not have had an aerodynamic function until after bipinnate, closed pennaceous feathers (stage IV) had evolved. (
  • It even has little pennaceous feathers on its head. (
  • The new conclusion was provided by the first discovery of feathered dinosaurs in the Western Hemisphere, a feat reported in the journal Science. (
  • Fossilized dinosaur scrape marks in 100-million-year-old Dakota sandstone of western Colorado reveal that dinosaurs engaged in mating displays that were similar to those of today's birds. (
  • Wonderful art and great writing earn Dinosaurs: Fossils and Feathers, a new Science Comics volume , an A+! (
  • Examples of ancient feathers ranging from the simple to the complex are now being studied. (
