The Geosteinbergia is one of the more demanding of the flying reptiles, requiring the largest aviary out of all the available species, including the massive Tropeognathus. While their environnemental needs are superior to the rest of the fliers, other than that they exhibit similar behaviors to it's close cousin the Pteranodon, spending it's days soaring in the aviary or fishing with it's sharp beak for fish, sometimes pecking it's flockmates at the feeder.
A very large pterosaur, Geosternbergia had a massive 7 meter wingspan. Its most defining feature is the large and impressive crest found on male individuals, with females possessing a smaller crest. The purpose of these crests was most likely for mating displays, but others theorise pterosaur crests may have been used for aid when flying, either by making the animal more streamlined or allowing them to make sharper turns in the air like the rudder on an airplane. Geosternbergia lacked any teeth and fed on fish and other small marine life.
When its remains were found in 1952, it was assumed to have been a species of Pteranodon due to their similar shape and size. Thus in 1966 it was named as Pteranodon sternbergi. A thorough study in 1978 after additional fossils were uncovered, enough differences were found to move it to a new genus.
Geosternbergia remains have been found in the Niobrara Formation, Pierre Shale and Smoky Hill Chalk. These Cretaceous formations harbour a large variety of marine life, including various fish, marine reptiles and other pterosaurs such as Nyctosaurus.
