| One thing that is quite bizarre about the tyrannosaurs are their tiny little forelegs. |
| Holtz ultimately concludes that ornithomimosaurs and tyrannosaurs probably form a monophyletic group, although his calculations do not yield a clean separation. |
| Other evidence, though, suggests tyrannosaurs were gregarious. |
| The large carnosaurs and tyrannosaurs also appear to have shorter teeth than would be expected for a mammalian carnivore of their body size. |
| Most predatory dinosaurs such as tyrannosaurs and velociraptors have usually been depicted in museums, films and books as covered in a thick hide of dull brown or green skin. |
| Because feathers are a unique feature, they are thought to be characteristic of many theropod dinosaurs, including tyrannosaurs. |
