What dinosaur flew?

Answer 1

Up until recently, it was believed that NO dinosaur ever flew. Pterosaurs such as Ramphorynchus and Pteranodon are commonly referred to as 'flying dinosaurs', but they are really fur-covered relatives that evolved slightly earlier. Either way, most animals that fit under the public interpretation of 'dinosaur' didn't fly.

However, those are scientifically considered 'non-avian' dinosaurs. For about as long as we've known that there were dinosaurs, we've had evidence of bird-like dinosaurs or, even stranger, dinosaur-like birds. In fact, it's rare and almost improper to say that a bird isn't a type of dinosaur. We can take this logic to say that, after the cretaceous, all but a handful of dinosaurs learned to fly. (Excepting, of course, ostriches, penguins, kiwis, and the like.)

Answer 2

Actually, none of the dinosaurs flew. Ancient reptiles that lived along dinosaurs called pterodactyls actually could fly.

Answer 3

No dinosaurs flew because they did not have wings.
