Geosternbergia from the Late Cretaceous period of Kansas was one of the largest pterosaur genera and had a wingspan of up to 7.25 meters (23.8 feet). Geosternbergia was traditionally considered a species, or occasionally subgenus, of the similar pterosaur Pteranodon in most major studies of pteranodontians through the 1990s. However, a 2010 review of the group by A.W.A. Kellner suggested that Pteranodon sternbergi was different enough from P. longiceps to belong in a distinct genus, to which Kellner also referred a new species, Geosternbergia sternbergi.
The Lost World: Jurassic Park
Proven to be on the island by Roland’s dinosaur guide, the trailer’s screensaver, and by several drawings and models made for the film, the animal itself is never physically seen in any scene of the film. It has been suggested that the intended use for this species was to be the male sexually dimorphic version of the P. longiceps species seen at the very end of The Lost World: Jurassic Park.
Geosternbergia appears as a wildlife ambiance in the video game The Lost World: Jurassic Park; especially, on the Sulphur Fields level.
It also appears in the Site B lab in The Lost World: Jurassic Park arcade game. While the player are on a zipline trying to reach the lab, a flock of Geosternbergias attack the player before being shot by the player.
