The Genus Pterodactylus, a group of prehistoric flying reptiles from the Late Jurassic Period, is synonymous with several names. These names represent different species within the genus, including Ornithocephalus, Aerodactylus, Gnathosaurus, and Paleoornis. While these different names suggest distinct evolutionary developments within the genus, they all share certain physical characteristics. These features include a long, toothless beak, hollow bones to minimize body weight, and membranous wings made up of skin and muscle. Despite their distinct species names, these pterosaurs are all part of the Genus Pterodactylus, and they remain some of the most fascinating and mysterious creatures that once roamed the earth.
