Did dinosaurs have ears?

If you mean outer ears like ours, the honest answer is... we don't know. External lugs are made of non-fossil-ating material so the chances of discovering one that belonged to a dinosaur, if they even had them, are slim. Neither reptiles nor most birds (dinosaur's closest living relatives) have protruding ears so it's probably safe to assume that dinosaurs didn't have them either. The inner ear, however, is something else entirely, and dinosaurs definitely had a pair of those.

Using new-fangled scanning techniques on dinosaurs such as Itemirus, scientists have concluded that their inner ear's bony labrynth, the part of the ear hidden within the skull, was as much for balance as for hearing.
