species & Fun Facts:  Mosasurus  

 

The Mosasaurus appears in three Jurassic World movies:

*Jurassic World: The Mosasaurus is introduced as the star of a Sea World-like show and eats a genetically modified indominus rex.

*Fallen Kingdom: The Mosasaurus attacks a fishing trawler.

*Dominion: The Mosasaurus appears in this 2022 movie.

Mosasurus lived in the late cretaceous Period.  They were not land Dinosaurs, but were actually giant lizards that grew up to 57 feet long. They are often referred to as the "Dinosaurs of the Sea" due to their large size.  They are of a family of enormous marine reptiles that dominated the seas 66 to 90 million years ago.  They adapted from living on the land to living in the water, evolving to have tails similar to a shark and paddle-liker limbs.  These features made then very fast swimmers!  They lived near the surface of the ocean and did not swim very deep.  The Mosasaurus ate Fish, Turtles, smaller Mosasaurus , Ammonites, and other sea animals.  They had double-hinged jaws which enabled them to gulp down their prey whole.  They are considered to be some of the fearsome predators to ever inhabit our oceans. They first emerged during the Cretaceous period 90 million years ago, and become the oceans dominant predators with the with the extinction of the ichthyosaurs and decline of plesiosaurs. Mosasaurs went extinct during the Cretaceous-Paleogene extinction event which killed all of the dinosaurs.

A Mosasaurus is comparable to a modern day Komodo Dragon.  The Mosasaurus is one of the most Terrifying predators to live in Earths oceans.
