Paleontology portal History of science portal Dinosaurs portal Paleontology or palaeontology (from Greek: paleo, ancient; ontos, being; and logos, knowledge) is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2016.

The Garden Park National Natural Landmark in central Colorado U.S.A. was established for 40 acres (0.16 sq. km) by the U.S. National Park Service in 1973 in recognition of its historical and paleontological significance. It was here that rather complete dinosaur skeletons were first discovered in great abundance and diversity in the late 1800s, sparking a growth in worldwide interest in dinosaurs. The dinosaur quarries played an important part in the Bone Wars in the early history of American paleontology. Despite the National Natural Landmark designation, human-caused environmental deterioration continued. Not until passage of the Federal Land Policy and Management Act (FLPMA) in 1976 did the Bureau of Land Management reassess the negative environmental impacts of public lands in Garden Park. A series of studies led to incremental protection of the environment and paleontological resources, beginning with the establishment of a Research Natural Area in 1987, then a larger Area of Critical

Agassiz wrote that evidence of the existence of a Creator, constantly and thoughtfully working among the complicated structures that He has made is found throughout the natural world.2 He concluded that in the living world is clearly seen the intervention of an intelligent Creator and that when we evaluate the living world we can see the mental operations of the Creator at every step.3. Education. Agassiz was born in the village of Montier in the French-speaking part of Switzerland. Like many naturalists of the time, Agassiz was educated as a physician. He studied with several prominent German biologists, including zoologist Lorenz Oken and embryologist Ignatius Döllinger. After receiving his medical degree from the University of Erlangen in 1830, he traveled to Paris to study comparative anatomy under the most renowned comparative anatomist in all Europe, Baron Georges Cuvier.4. Cuvier, the founder of the field of paleontology, was so impressed with Agassizs work on fossil fish that he ...

Paleobiogeography has advanced as a discipline owing to the increasing utilization of a phylogenetic approach to the study of biogeographic patterns. Coupled with this, there has been an increasing interdigitation of paleontology with molecular systematics because of the development of techniques to analyze ancient DNA and because of the use of sophisticated methods to utilize molecules to date evolutionary divergence events. One pervasive pattern emerging from several paleontological and molecular analyses of paleobiogeographic patterns is the recognition that repeated episodes of range expansion or geo-dispersal occur congruently in several different lineages, just as congruent patterns of vicariance also occur in independent lineages. The development of new analytical methods based on a modified version of Brooks Parsimony Analysis makes it possible to analyze both geo-dispersal and vicariance in a phylogenetic context, suggesting that biogeography as a discipline should focus on the analysis ...

The Early-Mid Mesozoic was a time of broad ecological and geochemical change punctuated by two major biotic and environmental crises - the end-Permian and end-Triassic mass extinctions. In the wake of the end-Permian mass extinction, the Modern Fauna emerged as the dominant taxonomic group. Herein, bioclastic accumulations are used to track ecological dominance across the Early Mesozoic, particularly in the Middle Triassic aftermath of the end-Permian mass extinction interval. Additionally, a literature search is used to trace the waning ecological importance of the crinoids, constituents of the Paleozoic Fauna, through the Mesozoic. Despite diminished diversity, the Paleozoic Fauna regained ecological dominance in the post-extinction world. After a Middle Triassic comeback, the crinoids persisted as ecological dominants through the Jurassic before their ecological twilight in the earliest Cretaceous. The timing of these patterns does not fit the suggestion of an ecological upheaval caused by ...

This specimen most likely came from an unidentified Sauropod dinosaur. There have never been any bone fragments found in any of these specimens, indicating each one came from a meat-eater, so the presumption has been that these coprolites were plant-based in nature and came from herbivores.. A coprolite is fossilized feces. (Fossil Poop) Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animals behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words κόπρος (kopros, meaning dung) and λίθος (lithos, meaning stone). They were first described by William Buckland in 1829. Prior to this they were known as fossil fir cones and bezoar stones. They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to over 60 centimetres.. Coprolites, Like other fossils, have had much of ...

Studying fossils used to have one major drawback: you had to have your hands on the actual fossil. Thomas Adams and his colleagues from Southern Methodist University found a solution that would allow paleontologists (and interested lay persons) around the world to study the same fossil. They proposed making high-resolution 3D scans of the objects and disseminating them for free.. The team used portable 3D laser scanners to digitally archive the footprint (shown above) of a large meat-eating dinosaur. The footprint, Eubrontes glenrosensis, was part of a deteriorating walkway in Dinosaur Valley State Park, Texas. Thanks to the efforts of Adams et al., the 3D digital model is now free for anyone to download. By the way, if youre wondering why youve never heard of E. glenrosensis, its because thats the name of the trackway, not the dinosaur that made the prints, which is believed to be Acrocanthosaurus tokenensis. Because its impossible to prove which dinosaur left a print, footprints are given ...

Although the taxonomic affinities of the tubular body fossils, erniettomorphs and other problematic body fossils are not well understood, the data presented herein and in other recent fossil reports [21,32,65,71-73] from late Ediacaran strata in a range of taphonomic modes (e.g. pyritization, carbonaceous compressions, casts and moulds) have made it increasingly apparent that a morphologically diverse assemblage of macroscopic organisms comprising at least two disparate phyla existed at the end of the Ediacaran Period. Specifically, the co-occurrences of Ernietta, Conotubus, Corumbella, and Gaojiashania in terminal Ediacaran strata in Nevada biostratigraphically link a number of late Ediacaran fossil localities globally to validate the existence of a distinctive cosmopolitan biotic assemblage at the close of the Proterozoic, providing support that the Nama assemblage represents true biological turnover within the Ediacaran Period rather than reflecting provincial, palaeoecological or taphonomic ...

While rare in North America, toothed pterosaurs belonging to the Ornithocheiridae are a major component of Cretaceous pterosaur faunas elsewhere in the world, Myers says. The Texas specimen (right) - a nearly complete mandible with most of its 54 teeth missing - is definitively younger than most other ornithocheirid specimens from Brazil, England and China, he says. It is five million years younger than the only other known North American ornithocheirid.. Myers describes the new species in the latest issue of the Journal of Vertebrate Paleontology. He named the pterosaur Aetodactylus halli after Lance Hall, a member of the Dallas Paleontological Society who hunts fossils for a hobby. Hall found the specimen in 2006, embedded in a soft, powdery shale exposed by excavation of a hillside next to a highway near Mansfield. He donated the specimen to SMU..

One of the most profound and strangest discoveries in marine mammal paleontology is the discovery of aquatic adapted sloths from the Miocene and Pliocene of Peru (and now Chile as well). These were first named Thalassocnus in 1995, and in the following decade a number of additional species and a ton of skeletons were reported and described. Common questions I get about these from colleagues in non-mammalogical fields of paleontology are How do we know theyre actually aquatic and not just terrestrial sloths that floated out to sea?. Its an excellent question that can be addressed taphonomically and adaptationally. Taphonomically speaking, these skeletons have only been found in marine sediments and none yet from terrestrial deposits - which have other types of sloths. Further, apparently much of the coastline of Peru during the late Neogene was inhospitable desert. These sloths also have modified limb proportions and large muscle attachment areas on caudal vertebrae for undulation of the tail ...

Though undeniably speculative when it was published in 1998, The New Dinosaurs was greatly influenced by the state of dinosaur science at the time. By the late 1980s the cultural shift in paleontology celebrated as the Dinosaur Renaissance was in full swing-images of slow, stupid, swamp-bound and drab dinosaurs were rapidly being replaced by visions of active, agile and vividly colored animals that were far more bird-like than previously imagined. There was even a growing body of evidence that birds were the direct descendants of dinosaurs, and Dixon extrapolated from these paleontological trends to create a collection of colorful, behaviorally complex dinosaurs unlike any seen before. ...

Agadez region, Niger) differs significantly from those of the Jurassic sauropods examined, except potentially for Atlasaurus imelakei (Tilougguit Formation, Morocco). The basisphenoids of Spinophorosaurus and Atlasaurus bear basipterygoid processes that are comparable in being directed strongly caudally. The Spinophorosaurus specimen was CT scanned, and 3D renderings of the cranial endocast and inner-ear system were generated. The endocast resembles that of most other sauropods in having well-marked pontine and cerebral flexures, a large and oblong pituitary fossa, and in having the brain structure obscured by the former existence of relatively thick meninges and dural venous sinuses. The labyrinth is characterized by long and proportionally slender semicircular canals. This condition recalls, in particular, that of the basal non-sauropod sauropodomorph Massospondylus and the basal titanosauriform Giraffatitan ...

At Deep Sea Drilling Site 384 (J-Anomaly Ridge, Grand Banks Continental Rise, NW Atlantic Ocean) Paleocene nannofossil chalks and oozes (similar to 70 m thick) are unconformably/disconformably underlain (similar to 168 m; upper Maastrichtian) and overlain (similar to 98.7 m; upper lower Eocene) by sediments of comparable lithologies. The chalks are more indurated in stratigraphically higher levels of the Paleocene reflecting increasing amounts of biosiliceous (radiolarians and diatoms) components. This site serves as an excellent location for an integrated calcareous and siliceous microfossil zonal stratigraphy and stable isotope stratigraphy. We report the results of a magnetostratigraphic study which, when incorporated with published magnetostratigraphic results, reveals an essentially complete magnetostratigraphic record spanning the interval from Magnetochron C31n (late Maastrichtian) to C25n (partim) (late Paleocene, Thanetian). Integrated magnetobiochronology and stable isotope ...

I also have a paleontology interest in the nesting behaviors of birds. Birds are modern-day (or extant, for the technical term) theropod dinosaurs! There is great fossil evidence that theropod dinosaurs also engaged in nest building, active egg incubation, and parental care that is similar to what we see in modern birds. The best example (and best-known science story) of bird-like brooding in theropods is with Oviraptor philoceratops (the egg thief that loves ceratopsians). This story begins with the initial interpretation of thievery to explain its presence on a dinosaur nest full of eggs (thought to be the eggs of Protoceratops), and an associated skeleton of a predatory dinosaur with a toothless beak: both pieces of information led the researchers of the day (Osborn 1924) to suggest that Oviraptor was well-suited - and took advantage of - a diet that included eggs. Norell et al. (1999) examined an oviraptorid skeleton found in a similar position as the original Oviraptor specimen - a skeleton ...

Sinosaurus has left its mark across much of China and a great deal of paleontology that has been published from China. The literal mark making is documented in trackways, though these are rare (compared to those in North America) and are not completely diagnosable. To that end, a small number of theropods are discussed whenever trackways are found. Sinosaurus has found its way into those discussions as a stand in (literally) foot model for some theropods and as a contributor to these trackways. Xing et al. 2014 discusses both of these possibilities in regard to newly discovered trackways in central China. Trace fossils of predators are typically represented either by the trackways above or by lost teeth. The benefit, to us and theropods, of lifetime tooth replacement is that we can find fossilized teeth and theropods never have to go hungry. Whenever teeth fall out, the bone that holds those teeth remodels as new teeth grow in. This loss and remodeling is the subject of a description of the ...

Dinosaur paleontology has long been the domain of bones and teeth - but now soft tissues could be changing the game. Scientists say they have discovered collagen preserved in a 195-million-year-old rib from a long-necked Lufengosaurus. The protein fragments, described in the journal Nature Communications,...

Fossils: Traces Of Ancient Life From The Sea & The Land will introduce you to the Geologic Time Scale, Paleontology, and fossils of all kinds. You will learn the definition of a fossil. There are drawings and information about fossils from ancient algae (stromatolites) to marine fossils, to insects, plants, spiders, Archaeopteryx, and dinosaurs, of course. You will even discover fossilized dinosaur doo-doo! And just like all our books, there are activities to do (like making your own fossils at home!), word search puzzle and more ...

The White River Badlands contain the largest assemblage of known late Eocene and Oligocene mammal fossils. Fossil research from the area contributed significantly to the science of vertebrate paleontology in North America, beginning with the description of a titanothere mandible in 1846 by Dr. Hiram Prout. Since then numerous important finds from the area have informed scientists about ancient animals, climates, and ecosystems from different geologic time periods. Oligocene fossil remains include camels, three-toed horses, oreodonts, antelope-like animals, rhinoceroses, deer-like mammals, rabbits, beavers, creodonts, land turtles, rodents and birds.. Marine fossils are found in deposits of an ancient sea that existed in the region some 75 to 67 millionyears ago during the Cretaceous period. Fossils found in the Pierre Shale and Fox Hills Formations include ammonites, nautiloids, fish, marine reptiles, and turtles.. The spectacular vertebrate fossils preserved within the White River Badlands have ...
