In Jurassic World, what is the name of the park’s giant marine reptile?

The giant marine reptile displayed at Jurassic World is a Mosasaurus.

In the 2015 film, the Mosasaurus lives in a large aquatic attraction where visitors watch it leap from the water to seize prey. Its dramatic feeding-show sequence introduces the park as a fully operational resort and demonstrates how Jurassic World packages prehistoric animals as entertainment.

Mosasaurus was not a dinosaur. It was a marine lizard belonging to the mosasaur family, which lived during the Late Cretaceous Period. The movie presents the animal at an enormous size, and paleontological estimates for real mosasaurs vary by species and fossil evidence.

The creature returns in later Jurassic World films, including Fallen Kingdom and Dominion. The spelling is commonly confused with “Mosasaurus,” but the animal’s name is based on the Meuse River region where related fossils were first identified.
