'''Pterosaurs''' (Greek "winged lizards") are an extinct order of flying reptiles that lived during the [[Mesozoic Era]]. They are believed to be the first vertebrates to achieve powered flight. Their varied skull morphology allowed them to exploit numerous food sources, and they ruled the air until the K-T extinction event.
