Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
Rhamphorhynchus (/ ˌ r æ m f ə ˈ r ɪ ŋ k ə s /, [1] from Ancient Greek rhamphos meaning "beak" and rhynchus meaning "snout") is a genus of long-tailed pterosaurs in the Jurassic period. . Less specialized than contemporary, short-tailed pterodactyloid pterosaurs such as Pterodactylus, it had a long tail, stiffened with ligaments, which ended in a characteristic soft-tissue tail va
The fossil trackways show that pterosaurs like Hatzegopteryx were quadrupeds, and some rather efficient terrestrial predators. Pterosaurs' hip sockets are oriented facing slightly upwards, and the head of the femur (thigh bone) is only moderately inward facing, suggesting that pterosaurs had an erect stance. It would have been possible to lift ...
Pterodactyloidea (/ˌtɛrəˈdækt͡ɬɔɪdɪːə/; derived from the Greek words πτερόν (pterón, for usual ptéryx) "wing", and δάκτυλος (dáktylos) "finger") [1] is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles.
Like many pterosaurs and birds, it possessed a notarium, a fused mass comprising the first six dorsal vertebrae. [25] Similarly, the first few ribs were fused. [15] The pelvic bones were fused to the synsacrum, a mass of vertebrae that included at least two dorsal vertebrae, [17] the sacral vertebrae, and the first caudal vertebra. [15]
Pterosauromorpha (meaning "pterosaur-like forms") is one of the two basic divisions of Ornithodira that includes pterosaurs and all taxa that are closer to them than to dinosaurs and their close relatives (i.e. Dinosauromorpha).

Avemetatarsalia (meaning "bird metatarsals") is a clade of diapsid reptiles containing all archosaurs more closely related to birds than to crocodilians. [2] The two most successful groups of avemetatarsalians were the dinosaurs and pterosaurs.
