Most people think of pterosaurs as "flying dinosaurs". When I was a boy, I remember the other kids called them "dinosaur-birds", but they were neither dinosaurs or birds. The first problem is that most people don't know any more about the fossil record than what they've seen in a few plastic pieces in a prehistoric playset. Not only do they typically think that all these things are dinosaurs, they might even think that these are all the fossil forms that are known. They have no idea how rich the fossil record is.
