Pteranodon is a type of pterosaur which lived during the Late Cretaceous period in present day Kansas, Alabama, Nebraska, Wyoming, and South Dakota in the United States. Similar to modern birds, pteranodon, unlike other pterosaurs, had no teeth, hence its name, meaning toothless wing. The most distinctive characteristic of the pteranodon is its cranial crest which consisted of bones which projected up and back from the skull. By definition, pteranodon is a reptile, though many people think of it as a dinosaur. The pteranodon is among the largest of the pterosaurs.

Scientists think that pteranodon would have flown like a modern-day albatross. Much of its flight would have been gliding, though it's winspan to weight ratio suggests it was capable of short bursts of rapid wing flapping.


  • Estimated weight: from 23 kg. (44 pounds) to as much as 93 kg. (210 pounds)
  • Male wingspan: 6.25 meters (20.5 feet)
