#13: Tylosaur skull
Also obtained in fall of 2005 and also over 3 feet long, this cast of a tylosaur skull "in situ" came from the Mt. Blanco fossil museum.
Considered to be a type of Mosasaur, the tylosaurs were marine creatures. They looked vaguely like a crocodile with flippers instead of legs, with a long, powerful and streamlined tail.
This particular skull was about half the size of the largest ever found in the U.S., coming from a skeleton over 15 meters long.
