This specimen, the largest mosasaur ever found in North America, was collected in 1911. It was placed in the collections of a major university in the US, where it remained in storage until 1997, when it was restored by Triebold Paleontology, Inc.
As the dominant predator of the seas, the Tylosaurus diet consisted of other sea creatures – basically, anything it chose to eat!
Both the Tylosaur and Platecarpus bones have been found with evidence of necrosis, resulting from a long stay at extreme depths. No such necrosis has yet been found in Clidastes bones which suggests that they did no deep diving therefore filling a difference niche.
