Pteranodon
Pteranodon (; from Greek πτερόν ( pteron, "wing") and ἀνόδων (anodon, "toothless") is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 8 meters (26 feet). They lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. More fossil specimens of "Pteranodon" have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway.
Barbosania
"Barbosania" was a medium-sized pterodactyloid with a skull length of 392 millimetres. Its body was 209.5 millimetres long. The skull is elongated with a slight upwards bend in the snout. Its lack of a rostral and dentary median sagittal crest allows a distinction from other related pterosaurs. Also a parietal crest on top of the skull is absent. The authors considered it unlikely that this morphology was age-related and rejected the explanation of such traits by sexual dimorphism unless there was specific evidence to prove this. The describers established a single autapomorphy, unique trait: the possession of thirteen dorsal vertebrae instead of the normal twelve. The first four tooth pairs are extremely long, forming a rosette to catch slippery prey like fish or squids. This rosette is however not laterally expanded, which was reflected in the specific name. There are at least twenty-four teeth in the upper jaw and twenty in the lower jaw for a total of eighty-eight.
