T. proriger specimen which was found with a plesiosaur in its stomach

Tylosaurus was an Upper Cretaceous mosasaur. It was a large, predatory marine lizard closely related to modern monitor lizards and to snakes.

In 1918, Charles H. Sternberg found a Tylosaurus, with the remains of a plesiosaur in its stomach.[1] The specimen is currently mounted in the United States National Museum (Smithsonian) and the plesiosaur remains are stored in the collections. Although these important specimens were briefly reported by C.H. Sternberg (1922), the information was lost to science until 2001. This specimen was rediscovered and described by Everhart. It is the basis for the story line in the new (2007) National Geographic IMAX movie - Sea Monsters.[2]
