Did T. rex really have feathers?
Paleontologists think feathers may have first evolved to keep dinosaurs warm. But while a young T. rex probably had a thin coat of downy feathers, an adult T. rex would not have needed feathers to stay warm.
Did the dinosaurs have feathers?
The first dinosaur fossils with structures that could be considered feathers were found in the 1990s. Even though the first dinosaurs are thought to have emerged some 245 million years ago, dinosaurs with feathers have been dated to only 180 million years ago.
What did feathers do for dinosaurs?
At least one dinosaur apparently used its feathers for defence, and this may have been a viable strategy for other. Still bristles on the animal may have made them harder to attack or eat and provided a useful defence against some predators, or even parasites (if also making them more vulnerable to others like fleas).
What is a feathered dinosaur called?
Feathered dinosaurs is a term used to describe dinosaurs, particularly maniraptoran dromaeosaurs, that were covered in plumage; either filament-like intergumentary structures with few branches, to fully developed pennaceous feathers complete with shafts and vanes.
Was T Rex a roadrunner or a lizard?
Paleontologist Robert Bakker memorably described T. rex as “the 20,000-pound roadrunner from Hell” and modern research bears him out. Even the largest dinosaurs probably looked more like a Greater Roadrunner than a lizard. Photo by Glenn Bartley.
Were dinosaurs really bird-like?
When paleontologists say that dinosaurs were birdlike, they’re talking about more than just feathers.
Fossils of Archaeopteryx include well-preserved feathers, but it was not until the early 1990s that clearly nonavian dinosaur fossils were discovered with preserved feathers. Today there are more than twenty genera of dinosaurs with fossil feathers, nearly all of which are theropods. Most are from the Yixian Formation in China.
