More than likely considering that reptiles are said to be closely related to birds. Back in the day dinosaurs would have been cross bred DNA of both a bird and reptile since they are so close, therefor being all the proof we need.
Why not? All we have left of them are there skeletons, we don't really know what the skin would have looked like. However, I must say that a fluffy tyrannosaurus rex would have looked hilarious.
dinosaurs are not reptiles...they are birds......amphibians are more likely related to reptiles
they have actually found feathered dinosaurs so yes
