Fossil skull of pterosaur
Pterodactylus, a pterosaur of the late Jurassic period, is characterized by a lightweight and compact skull composed of thin, hollow bones. Its first finger is particularly elongated to support membrane wings, and its hind limbs are short. All members of the Pterodactylidae family have short tails and long heads. Some species of pterosaurs have a body size similar to sparrows; Others can be as big as eagles, with wings extending up to 30-70 centimeters, feeding on insects, and some may forage for fish. The entire group of pterosaurs is a suborder of pterosaurs. In terms of classification, it does not truly belong to dinosaurs, but is only a close relative of dinosaurs.
