Pterosaurs were the flying reptiles of the extinct clade Pterosauria that flourished during all periods (Triassic, Jurassic, and Cretaceous) of the Mesozoic Era about 228 to 66 million years ago. Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. Earlier species had long, fully-toothed jaws and long tails, while later forms had a highly reduced tail, and some lacked teeth. Pterosaur bones were hollow and air-filled, like those of birds which provide them with a higher muscle attachment surface for a given skeletal weight. The bone walls were often paper-thin and they had a large and keeled breastbone for flight muscles and an enlarged brain able to coordinate complex flying behavior.
