A pterosaur ("winged lizard") was a flying reptile (commonly referred to as a pterodactyl -- "wing finger") of the order Pterosauria. They existed from the late Triassic to the Cretaceous periods (from 228 to 65 million years ago). The earlier species had long, fully-toothed jaws and long tails, while later forms had a stump for a tail, no teeth and a jaw more like a beak than the elongated jaw of the earlier species. |
