Pterodactyloidea describes a group of winged dinosaurs (Pterosauria). Fossils were found in England, Bavaria and at Tendaguru. These flying reptiles lived in the Lower Jurassic up to the Cretaceous/Tertiary borderline 65 million years ago. They were the first vertebrates able to fly. Birds only emerged towards the end of the Jurassic periods, bats even significantly later. Flying dinosaurs laid eggs and were presumably able to fly as soon as they hatched. The largest pterodactyl had a wingspan of 11 metres!
