Tylosaurus proriger

pronounced (Tie-Low-Sore-us  Pro-Rig-er)


Nick Name: “Bunker Tylosaur”
Discovered By: C.D. Bunker, 1911
Discovery Location: Western Kansas
Diet: Meat Eater (Carnivore)
Period: Late Cretaceous
Age: 83 million years
Formation: Niobrara Chalk
Lenght: 45 ft.
Location of Original Specimen: In the Collection of The University of Kansas Museum of Natural History, Lawrence, Kansas

This specimen, the largest mosasaur ever found in North America, was collected in 1911. It was placed in the collections of the University of Kansas where it remained in storage until 1997, when it was restored and molded 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 Tylosaurus and Platecarpus bones have been found with evidence of avascular necrosis resulting from a long stay at extreme depths. Avascular necrosis (also known as the bends) has not been found in Clidastes bones which suggests that they did no deep diving, therefore filling a different ecological niche.
