Pteranodon sternbergi is an extinct species of the pteranodontid pterodactyloid pterosaur genus Pteranodon from the Late Cretaceous geological period of North America. P. sternbergi was among the largest pterosaurs, with a wingspan of up to 6 metres (20 ft) in males. It has been argued that P. sternbergi should be classified in a separate genus, Geosternbergia, but this has not been followed by most researchers.

fossil Geosternbergia Pteranodon Pterosauria taxonomy
 This week we are looing at a famous pterosaur.  Check out Geosternbergia sterngergi!  I'm going to start this post off with pointing out that Geosternbergia is considered simply a separate species within the genus, Pteranodon, by many experts, which would make its name Pteranodon sternbergi.  That being said, since I already did a post on Pteranodon longiceps, I'm choosing to refer to this pterosaur as Geosternbergia.  (taxonomy is complicated and also subject to change especially with fossils)
