Your links are so crappy though. Here are two better ones: http://en.wikipedia.org/wiki/Pterosaur and http://en.wikipedia.org/wiki/Dinosaur You do realize you're just being picky. Moreover, Dr.Grass' statement mentioned that Dinosaurs all evolved flight. So for instance a Dino could have evolved into a Pterosaurus. He never said Dinos flew. The only difference between a Dinosaur and a Pterosaur is in the terminology. Dinos by definition are vertibrate with a unique upright stance. That's the only difference. Otherwise for all suits and purposes Pterosaurs are "saurs" and lived the same period as dinos. Dinos and Pterosaurs are reptilian that are dated to the Triassic to Cretaceous period. They are also "terrible" lizards (some can span 10 meters (33ft) across the wings), have a dino-like fossil and are extinct. To understand how wide 10m is for a wingspan, compare that to this list: http://en.wikipedia.org/wiki/Largest_birds. None exceed 8 point some meters wingspan. Add to the fact that some birds are classified as dinos, it gets worse for your argument. Even then I don't see what you were trying to disprove in the first place. But to be fair, I learnt all this post research, and I do apologize for being unnecessarily rash. You're right, I shouldn't assume things and should research before claiming things. As they say, to assume makes and ass of u and me. |
Pterosaurs are not dinosaurs. There is no scientific definition in which they are considered dinosaurs. Also not all dinosaurs evolved flight, only one small group did - the rest went extinct. Dr.Grass was being condescending at the same time as being wrong which is never good.
