Pteranodon (Jurassic Park)

Pteranodon is a large flying reptile with a wingspan measuring as long as a school bus. These reptiles 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. Their diet was comprised of 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.[2]
