Pterosaur Facts
A pterosaur is any of the flying reptiles that lived throughout the Mesozoic Era (252.2 million to 66 million years ago) during all three periods (Triassic, Jurassic, and Cretaceous).
Although pterosaurs are not dinosaurs, they are archosaurs, or "ruling reptiles," which include birds and crocodiles.
They were also the first animals to evolve powered flight after insects, not just leaping or gliding, but flapping their wings to generate lift and move through the air.
Pterosaurs were not only the first reptiles to fly. They were the first vertebrates to fly as well.
It contained the late Cretaceous Quetzalcoatlus, the biggest creature ever known to fly.
Flight in pterosaurs evolved independently of flight in birds and bats; pterosaurs are not closely linked to either birds or bats and thus constitute a typical example of convergent evolution.
A complex membrane of skin spanning from the thorax to a drastically enlarged fourth finger constituted their wings.
Pterosaurs became extinct around the end of the Cretaceous period, around 65.5 million years ago, during the Cretaceous-Tertiary extinction event (K-T extinction event).
