| − | '''Pterosaurs''' (Greek "winged lizards") are an allegedly extinct order or [[apobaramin]] of flying [[reptile]]s. Their varied skull morphology likely allowed them to exploit numerous food sources. Pterosaurs can be divided into two separate clades or baramins: the pterodactyloids, which were toothless and often had head-crests, and the rhamphorhynchoids, which were typically smaller and had teeth. | + | '''Pterosaurs''' (Greek "winged lizards") are an allegedly extinct order or [[apobaramin]] of flying [[reptile]]s.
