While the first Pteranodon wing bones were collected by Marsh and Cope in the early 1870s, the first Pteranodon skull was found on May 2, 1876, along the Smoky Hill River in Wallace County (now Logan County), Kansas, USA, by Samuel Wendell Williston, a fossil collector working for Marsh. [7] A second, smaller skull soon was discovered as well.
The first fossils of Pteranodon sternbergi were collected by American paleontologist George F. Sternberg in 1952 from the lower portion of the Niobrara Formation.The fossils of the animal looked similar to those of the species Pteranodon longiceps, but the crests were set upright and in a slightly different position.
Pterosaur skeletons often show considerable fusion. In the skull, the sutures between elements disappeared. In some later pterosaurs, the backbone over the shoulders fused into a structure known as a notarium, which served to stiffen the torso during flight, and provide a stable support for the shoulder blade.
Pteranodontia is an extinct group of ornithocheiroid pterodactyloid pterosaurs.It lived during the Late Cretaceous (Turonian to Maastrichtian stages) of North America, South America, Europe and Africa. [1]
A nearly complete skull fossil found in Egypt has revealed a new species of Hyaenodonta, an apex carnivore that mysteriously went extinct about 25 million years ago.
Alexander Kellner, for example, named several additional species for specimens previously classified as Pteranodon, and placed P. sternbergi in a distinct genus, Geosternbergia. Kellner re-defined Pteranodontidae as the most recent common ancestor of Pteranodon longiceps , Geosternbergia sternbergi and Dawndraco kanzai , and all of its descendants.
A 68-million-year-old skull fossil found in Antarctica has revealed the oldest known modern bird, which was likely related to the waterfowl that live by lakes and oceans today, according to new ...
