Pteranodon sternbergi is a species of Pteranodon, a pteranodontid pterosaur. It lived in the middle-late Cretaceous, about 85 million years ago, in North America. It lived on fish, and was among the largest of the flying reptiles, having a 9 m (30 ft) wingspan.[1] It was first described in 1966 and is believed to be an ancestor of the later species Pteranodon longiceps.[2]
[edit] Anatomy
Pteranodon sternbergi is the first known upright-crested species of Pteranodon.[3] It is believed that the crest kept it stable when flying.[4] The lower jaw of P. sternbergi was 1.25 meters (4 ft) long.[4]
