Pteranodon

Pteranodon is a large flying reptile. When it spread its wings, it could reach from the front to the back of a school bus. It did not have feathers, but rather had a basal type of integument along the same lineage from which feathers evolved, called pycnofibers. Pycnofibers were very hair-like in appearance and, like hair, were made of keratin.

Members of the Pterosaur order lived through much of the Mesozoic, some species of Pterosaurs with wingspans close to 11 meters (36 feet). Pteranodon males had a wing span of 5 meters (16 feet), while females had a wing span of 3 meters (10 feet), making the males one of the largest Pterosaurs found.

Pteranodon means "toothless wing", but in spite of this, it appears with teeth in one of the movies. It probably used the long crest on the back of its head to help it steer while flying. The movement is still some debate about whether these reptiles could actually fly or if they were primarily gliders, but the consensus seems to be that they could take off with little or no wind.

Their diet was fish and scavenged remains of dead marine animals. Quite a few Pteranodon skeletons have been found in Kansas in the central part of the U.S. This would have been the shore of a shallow sea when these creatures were alive, supporting the theory that they were fish eaters.
