Because the ASHCEs in genes such as Sim1 were highly conserved and therefore largely unchanged by evolution since the dinosaur era, this suggests CREs such as ASHCEs were vital in developing bird-specific traits and may have driven the transition of dinosaurs to birds. (phys.org)
Studying this group as a whole has yielded a wealth of knowledge for paleontologists, since pygostyles seem to mark the transition from the "long, straight, skinny tails of [dinosaurs] into the little, fused, stubby tails [birds] have today," Brusatte told Pickrell. (smithsonianmag.com)
Across the dinosaur-bird transition, the skull transforms enormously and the brain enlarges. (neurosciencenews.com)

These include Jurassic Park's Velociraptor , birds, and a huge range of other forms, weighing anything from 15 grams to 3 tonnes, and eating meat, plants, and more omnivorous diets. (science20.com)
Red and blue pigments were found in eggshells that belonged to the Eumaniraptoran dinosaurs like the velociraptor. (earth.com)
Oviraptors, a relative of the velociraptor, were the first known dinosaurs to lay their eggs in open nests and so it makes sense that eggshell pigment would be found in their family tree. (earth.com)
That means that birds, as a group, emerged well before T. Rex or the velociraptor. (zmescience.com)

In their own research, including one study just last year in the Journal of Morphology , OSU scientists found that the position of the thigh bone and muscles in birds is critical to their ability to have adequate lung capacity for sustained long-distance flight, a fundamental aspect of bird biology.

Early in the 20th century, birding (the practice of observing wild birds) grew in popularity. (adobe.com)

Recent discoveries of feathered dinosaurs from the older Middle-Late Jurassic period have reinforced this theory. (sciencedaily.com)
More recent discoveries, however, have revealed these dinosaurs were equipped with toothless beaks and likely omnivorous , eating a varied diet including fruits, plants and maybe even shellfish. (discovermagazine.com)
As more discoveries are made, we are constantly updating and changing our knowledge of what constitutes a dinosaur. (databasefootball.com)

Dec. 9, 2020 Molting is thought to be unorganized in the first feathered dinosaurs because they had yet to evolve flight, so determining how molting evolved can lead to better understanding of flight origins. (sciencedaily.com)

The hyper-efficient breathing system of birds is shared with alligators, and probably evolved in archosaurs, the common ancestor of crocodilians, birds and dinosaurs . (newscientist.com)
Per Ahlberg of Uppsala University in Sweden agrees that the efficient breathing system probably evolved in a common archosaur ancestor of crocodilians, birds and dinosaurs. (newscientist.com)
Actinopterygian fish, sharks, rays and chimaeroids, chelonioid sea turtles, marine crocodilians, polycotylid and elasmosaurid plesiosaurians, various mosasaurids and aquatic hesperornithiform birds collectively represented middle level and apex predators. (lu.se)
Comparative studies on birds and crocodilians may shed light on early archosaurian cognitive abilities as well as cognitive differences and/or similarities between birds and crocodylians. (lu.se)

For dinosaur enthusiasts, it's fascinating knowing that Jurassic Park is only ever as far away as a fertilized chicken egg. (sciencealert.com)
Early descriptions characterize the dinosaur as having a fragile crest and weak jaws, a description that influenced the depiction of Dilophosaurus in the "Jurassic Park" book and movie as a svelte dinosaur that subdued its prey with venom. (utexas.edu)

Birds, crocodiles and dinosaurs have much in common - including, it turns out, their breath. (newscientist.com)

The earliest known bird is Archaeopteryx ("ancient wing"), which lived around 150 million years ago in what is now southern Germany. (livescience.com)
Archaeopteryx is usually assumed to be on the bird line, but our analysis does not find this," says Hartman. (wisc.edu)

The results, published in the journal Nature , shed light on how the blue and red pigments found in many bird eggs today developed out of necessity when dinosaurs first started laying their eggs in open nests. (earth.com)
For two centuries, ornithologists assumed that egg color appeared in modern birds' eggs multiple times, independently. (earth.com)
Once dinosaurs started to build open nests, exposure of the eggs to visually hunting predators and even nesting parasites favored the evolution of camouflaging egg colors, and individually recognizable patterns of spots and speckles. (earth.com)
From the striking azure of an American Robin's egg to the Jackson Pollock-esque brown squiggles on a Great Bowerbird's, the diversity of colors and patterns in modern bird eggs derive from just two pigments: red and blue, or red-brown protoporphyrin IX and blue-green biliverdin. (evcforum.net)
Birds have long been considered unique for their colored shells, but as it turns out, those same exact pigments can be found in the eggs of certain dinosaurs. (evcforum.net)

All can trace their origins to a bipedal, mostly meat-eating group of dinosaurs called theropods ("beast-footed") that first appeared around 231 million years ago, during the late Triassic Period . (livescience.com)
Over many years, it has become accepted among palaeontologists that birds evolved from a group of dinosaurs called theropods from the Early Cretaceous period of Earth's history, around 120-130 million years ago. (sciencedaily.com)
That group of dinosaurs went on to become all the birds we see today. (zmescience.com)
There are obvious evolutionary links between this exceptional living group of birds and their Mesozoic relatives says Dr Roger Benson of Oxford University's Department of Earth Sciences, who led a study on dinosaur evolution . (zmescience.com)
The more notable dinosaurs of the group are the Stegosaurus and Iguanodon. (zmescience.com)
