Pterosaurs were the first reptiles to develop powered flight. They lived for a long time, from the Late Triassic to the End of the Cretaceous (228-66 million years ago). Although they are sometimes referred to as ‘flying dinosaurs,’ this is incorrect. Although they are closely related to dinosaurs, they are technically just outside of the group, so paleontologists refer to pterosaurs ad dinosaurs as ‘sistergroups’.
