Mosasaurus

This article is about the Mosasaurus, not to be confused with the  with the same name.

- Mosasaurus Feeding Show Announcer

Mosasaurus was a genus of large aquatic carnivore from the Late Cretaceous about 70-65 million years ago. Mosasaurus gave its name to a group of marine lizards - Mosasaurs.

Mosasaurus means 'Meuse Lizard', referring to the river near which it was first found. It fed on such prey as seabirds, sharks, large fish, plesiosaurs and even other mosasaurs.

Creation
Mosasaurus was successfully recreated by InGen under the wing of the Masrani Global Corporation for their new dinosaur park Jurassic World.

The Mosasaurus page and the Mosasaurus Feeding Show page on the Jurassic World website give conflicting accounts about its weight. The Mosasaurus page says it weighs 5 tons while the Mosasaurus Feeding Show says it weighs 15 tons. It is most likely 15 tons because that is a real estimate of Mosasaurus' weight and it is safe to assume the Mosasaur page on the Jurassic World website is a typo. On the website, it's been confirmed that the species is Mosasaurus maximus, a synonym of Mosasaurus hoffmanni.

Unlike the last mosasaur InGen recreated, the cloned Mosasaurus retained many features of its original counterpart, but there was a difference between the two. It also had a bite force of 13K, one pound higher than the terrestrial predator Tyrannosaurus rex that lived in the same period as the Mosasaur. The Mosasaur lived in a pool the size of 3,000,000 gallons of water located near Main Street known as the "Jurassic Lagoon" and visitors could watch it feed on sharks in the Mosasaurus Feeding Show. Visitors could also view her through an aquarium below the lagoon known as the Underwater Observatory to see her.

Isla Nublar Incident (2015)
Following the escape of the Isla Nublar Aviary's residents from their enclosure, Jurassic World employee Zara Young fell into the Mosasaurus' tank after being grabbed by a Pteranodon. When the Pteranodon flew over the top of the enclosure to recapture her, it was consumed by the Mosasaurus. It is currently unknown if the Mosasaurus also killed Zara, or even attacked her.

Behind the scenes
As revealed in an interview with Empire Magazine, 'Jurassic World director Colin Trevorrow came up with the idea of the Mosasaurus Feeding Show during one of his first meeting with Steven Spielberg and Frank Marshall. He mentions that in his original concept that there is a separate facility that mass produces the sharks the Mosasaurus eats via cloning.

The scene of the Mosasaurus feeding in has changed a total of 3 times with every trailer release so far. Similarly, the scene where the Mosasaurus jumps out of the water and kills the Pteranodon has changed twice.

Trivia
All video games released before have outdated depictions of Mosasaurus showing it without a tail fluke and lacking the color scheme that all mosasaurs might have had in real life, which was black with a white underbelly.
 * The cloned Mosasaur in captivity on Jurassic World is currently the only surviving member of her genus and her family.
