Pteranodon was a large pterosaur from the Upper Cretaceous period.

Appearance[change | change source]

With its wings open it was up to 6.25 meters across. Pteranodon might have live much like and albatross, spending a lot of time over the ocean, looking for fish. It had no teeth in its long mouth, and it had a small pouch like a pelican at the back of its jaw. Pteranodon had a big crest at the back of its head. Pteranodon longiceps had a straight crest that went backwards, and Pteranodon sternbergi had a bigger, flatter crest that went upward.

Pteranodons like modern birds did not have teeth in their beaks. This was unlike Pterodactylus which had teeth in their beaks.

Fossil Pteranodon have been found in Kansas, Alabama, Nebraska, Wyoming, and South Dakota.
