Jurassic World: Mosasaurus

Mosasaurus once ruled the Cretaceous seas. An immense seagoing lizard-and not an actual dinosaur-Mosasaurus can use its fearsome array of teeth to catch fish, birds and other marine reptiles-even great white sharks. In fact, Mosasaurus has a second set of teeth in its upper palate that ensures any prey sliding down its throat will not be able to escape.
