Well-known examples of pterodactyloids include Pterodactylus, Pteranodon, and Quetzalcoatlus. In 2014, fossils from the Shishugou Formation of China were classified as the most basal pterodactyloid yet found, Kryptodrakon. At a minimum age of about 161 my, it is about 5 million years older than the oldest previously known confirmed specimens. [3]
Alexander Kellner, for example, named several additional species for specimens previously classified as Pteranodon, and placed P. sternbergi in a distinct genus, Geosternbergia. Kellner re-defined Pteranodontidae as the most recent common ancestor of Pteranodon longiceps , Geosternbergia sternbergi and Dawndraco kanzai , and all of its descendants.
Pteranodon (/ t ə ˈ r æ n ə d ɒ n /; from Ancient Greek: πτερόν, romanized: pteron ' wing ' and ἀνόδων, anodon ' toothless ') [2] [better source needed] is a genus of pterosaur that included some of the largest known flying reptiles, with P. longiceps having a wingspan of over 6 m (20 ft).

Ornithocheiroidea (or ornithocheiroids) is a group of pterosaurs within the extinct suborder Pterodactyloidea.They were typically large pterosaurs that lived from the Early to Late Cretaceous periods (Valanginian to Maastrichtian stages), with fossil remains found all over the world except Antarctica.
In 1928, Charles Gilmore named a new species of Pteranodon: P. oregonensis.A humerus (holotype MPUC V.126713), two fused dorsal vertebrae and the broken-off end of some joint bone had been unearthed from the Lower Cretaceous (Albian stage) beds of the Hudspeth Formation in Wheeler County, Oregon, United States, to which the specific epithet refers.
A later study suggested that while smaller-bodied pterosaurs were most likely superprecocial or precocial, owing to the consistent or decreasing wing aspect ratio during growth, certain large-bodied pterosaurs, such as Pteranodon showed possible evidence of their young being altricial, due to the fast rate the limb bones closest to the body ...
Pterodon (Ancient Greek: πτερόν (wing) + ὀδούς (tooth) meaning "wing tooth") is an extinct genus of hyaenodont in the family Hyainailouridae, containing five species.
