Size Edit. Smoky Hills Chalk In Kansas - Remains of Pteranodon have been recovered from the Late Cretaceous Smoky Hills Chalk in Kansas including fossils showing evidence of scavenging by sharks. The pteranodon is a fossil that can be donated to the museum in all Animal Crossing series games and collected by Happy Home Handbook in Happy Home Designer. It is a three or four-part fossil, depending on the game - Wild World introduced a fourth part, the ptera body, which was removed in City Folk and continued to be excluded in New Leaf. Bennett interpreted this as indicating a more spacious birth canal, through which eggs would pass. Immature specimens are known from both females and males, and immature males often have small crests similar to adult females.

The three fossil … He suggested that the crest might have anchored large, long jaw muscles, but admitted that this function alone could not explain the large size of some crests.In 1943, Dominik von Kripp suggested that the crest may have served as a With these hypotheses ruled out, the best-supported hypothesis for crest function seems to be as a sexual display. He suggested that the crest might have anchored large, long jaw muscles, but admitted that this function alone could not explain the large size of some crests.In 1943, Dominik von Kripp suggested that the crest may have served as a rudder, an idea embraced by several later researchers.Alexander Kellner suggested that the large crests of the pterosaur With the above hypotheses ruled out, the best supported hypothesis for crest function seems to be as a sexual display. \ Pteranodon was a reptile, but not a dinosaur. In 1892, Samuel Williston examined the question of Williston was also the first scientist to critically evaluate all of the pteranodont species classified by Cope and Marsh.

This is consistent with the size variation seen in fossil specimens, where juveniles and females have small crests and males large, elaborate, variable crests.The sex of the different size classes was determined not from the skulls, but from the pelvic bones.

Official State Flying Fossil of Kansas. Pteranodon species are extremely well represented in the fossil record, allowing for detailed descriptions of their anatomy and analysis of their life history. The smaller class of specimens have small, rounded head crests and very wide pelvic canals, even wider than those of the much larger size class.
