***Tylosaurus*** is a genus of marine reptile in *Evolution 2*. It originated from Late Cretaceous North America.

## History

The *Tylosaurus* was recreated for the original Jurassic Park as the main attraction for the Marine Facility, which was scheduled to open 6 months after the main park as part of Phase II.

End of information based on Jurassic Park: The Game.

## Characteristics

*Tylosaurus* is a large marine reptile that existed in the Western Interior Seaway that ran through the US and Canada during the Late Cretaceous. One of the apex predators of its marine environment, *Tylosaurus* is also one of the largest mosasaurs ever to have existed - second to *Mosasaurus*, measuring 14 meters in length. Studies have shown that it fed on sharks, plesiosaurs and even other mosasaurs.

## Gameplay

### Behavior

*Tylosaurus* is an absolutely massive mosasaur marine reptile, its only rival being the even bigger *Mosasaurus* with which it fight to the death if given the occasion, often resulting in itself dying. Unlike *Mosasaurus* however, *Tylosaurus* lives comfortably in pairs in a large lagoon, and will live off the fish dispensed by feeders. Other than that it would behave similarly to other marine reptiles, simply wandering around and killing and eating smaller creatures if given the chance for guest entertainment, with which *Tylosaurus* gives a lot, being extremely popular and one of the highest rating among prehistoric animals. They sometimes brawl with the *Mosasaurus* and the *Kronosaurus* over territory.

## Paleontology

*Tylosaurus* was first described by Edward Drinker Cope in 1869, based on his analysis of a partial skull found in the Niobrara Formation in Kansas. Initially, knowledge of *Tylosaurus* was limited due to the lack of a complete skeleton, but further remains uncovered during the 20th Century have developed a much wider understanding of the genus, with numerous species of *Tylosaurus* now formally recognized.

### Paleoecology

*Tylosaurus* was one of several species of mosasaur extant during the final Maastrichtian stage of the Late Creteceous. It likely competed with *Mosasaurus* for territory and prey. It was the apex marine predator of the Western Interior Seaway which bisected North America in the Cretaceous period, around 80 million years ago, feeding on fish (including sharks), seabirds, pterosaurs, other marine reptiles and even dinosaurs. Its powerful tail and paddle-shaped limbs allowed it to swim quickly through the water, while its huge size and sharp teeth ensured that anything that crossed *Tylosaurus'* path was potential prey. Analysis of compression damage to the jaw of *Tylosaurus* fossils suggests that it rammed larger prey with its snout to stun it before returning to eat.

## Behind the scenes

*Tylosaurus* was first seen in Development Diary 2 which was released on 22nd September 2021. However, its name was unknown at the time.
