MemberCompsognathusJul-17-2013 2:43 PMDid all dinosaur bones display evidence of feathers? Like I can see velociraptor with a few feathers on it's body, but a Carno with feathers? Thats like saying one-day all dinosaurs would have evolved into birds and taught themselves to fly...ridiculous. Please let me know your opinion or the true facts of scientist.
~Thanks

MemberCompsognathusJul-17-2013 3:08 PMHerbivores, with the exception of the therizinosaurs, almost certainly did not have feathers. Now, the therizinosaurs probably did. There is direct evidence for raptors, including Velociraptor, that shows they had feathers. V-Raptor arm bones are now known to have little bumps on them that represent where the feather would embed itself in the bone. Other raptors have feather impressions around them. I don't think Utahraptor had feathers because it was one of the most primitive raptors.
Now, the large theropods are another story. Yutyrannus had feathers and this makes sense. The tyrannosaurs belonged to the same group of dinosaurs as Velociraptor. Juvenile Tyrannosaurus' probably had feathers as well. Now, members of the carnosaur group probably did not have feathers, with a few exceptions. Concavenator seems to have had quill-feathers on it's arms. If the large carnosaurs had feathers, it was probably only a few on the arms and maybe head.
