The one thing you should all know about pterosaurs is that there was never a pterodactyl, the closest thing you will get is pterodactylus.  But there was never a pterodactyl.

Pteranodon: The Pteranodon was one of the largest pterosaurs, with a wingspan of over 20 feet!  Pteranodon meaning winged and toothless which in my opinion makes no sense, but it was toothless and had massive wings so yah, I guess it made a little sense.  Pteranodon lived in flock of up to 3000!  Dipping and diving, it fed off fish and dead carcass’s of fallen Dinosaurs.  Pteranodon lived in the middle to late Cretaceous in the North North West (not quite North but not quite North West) of the United States of America
