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.
Pteranodon
It is likely that, as in other polygynous animals (in which males compete for association with harems of females), "Pteranodon" lived primarily on offshore rookeries, where they could nest away from land-based predators and feed far from shore; most "Pteranodon" fossils are found in locations which at the time, were hundreds of kilometres from the coastline.
