Yes, there is a lot of information available about the pterosaurs. They are a group of flying reptiles that lived during the Mesozoic Era, which lasted from 252 mya to 66 mya. Pterosaurs were the first vertebrates to fly, and they had wings that were supported by a membrane made up of thin layers of collagen fibers. Some species even had feathers on their wings.
