Did T. Rex Have Feathers?
A feathered T. rex? Probably so--at least when the animals were young. 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. Large warm-blooded animals--like T. rex or modern elephants--generate a great deal of body heat so they usually don't need hair or feathers to keep warm. This is probably why elephants, which are mammals, don't have much hair.

Uh... Yutyrannus?

Plus there are impresions of feathers on adult and infant T.rexes
