Pterosaurs were fossil flying animals which lived during the Triassic, Jurassic and Cretaceous Eras. They were around for about 150 million years, which is a vast amount of time. They became extinct about 65 million years ago at the same time as the dinosaurs. Humans have only been on this planet for 2 million years.
