History:
The first Pteranodon specimen was found in 1870 in Kansas by Othniel Marsh, the famous paleontologist from Yale University. Marsh recognized that it was a pterosaur, but it had no head, so he wasn't sure whether it was the same as the pterosaurs from Europe, or something new. A few years later, in 1876, some skulls were found, showing that Pteranodon was indeed completely different from any known pterosaur. Since then, well over 1000 Pteranodon fossils have been discovered, making it one of the best-known pterosaurs.
