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.
Ornithocheiromorpha (from Ancient Greek, meaning "bird hand form") is a group of pterosaurs within the suborder Pterodactyloidea. Fossil remains of this group date back from the Early to Late Cretaceous periods (Valanginian to Turonian stages), around 140 to 92.5 million years ago.
The name Ornithocheiroidea was originally defined as an apomorphy-based taxon by Christopher Bennett in 1994. It was given a relationship-based definition in 2003 by Alexander Kellner, who defined it as the least inclusive clade containing Anhanguera blittersdorffi , Pteranodon longiceps , Dsungaripterus weii , and Quetzalcoatlus northropi .

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 shows the huge flying reptile would have had an estimated wingspan of more than 2.5 metres.
Size of P. sternbergi male (green) and female (orange) compared with a human. Pteranodon sternbergi was among the largest pterosaurs, with the wingspan of most adults ranging between 3 and 6 meters (9.8 and 19.7 ft). No complete skulls of adult males have been found, but a nearly complete lower jaw has been estimated at 1.25 meters (4.1 ft ...
Diagram showing specialized skulls and teeth of various ctenochasmatid pterosaurs. Compared to the other vertebrate flying groups, the birds and bats, pterosaur skulls were typically quite large. [24] Most pterosaur skulls had elongated jaws. [24] Their skull bones tend to be fused in adult individuals. [24]
Size compared to a human. Pterodaustro had a maximum adult wingspan of approximately 3 m (9.8 ft) and a maximum body mass of approximately 9.2 kg (20 lb). [9] Its hindlimbs are rather robust and its feet large.
