Tylosaurus was a large mosasaur from the Cretaceous. It was the top predator of its time and its environment.

Physical appearance and biologyEdit

Behaviour and traitsEdit

Tylosaurus was a giant predator. It hunted slow moving prey like ammonites, birds and turtles as well as larger creatures like sharks and Elasmosaurus. Tylosaurus were not the fastest of predators. Instead of chasing its prey, Tylosaurus would stalk and then it was ambush its prey in a short burst of speed. Being caught in its jaw meant almost certain death.

Tylosaurus were vivparous creatures, meaning that they gave birth to live young. They would then nurse their young for a few weeks. Tylosaurus live in groups of around 20 individuals, probably to provide protection to their young.

In Sea MonstersEdit

The Deadliest Sea EverEdit

After a dive with an Archelon, Nigel Marven's boat was capsized by a family of Tylosaurus. As Nigel and his crew swam away from the predators, the Tylosaurus attacked the over-turned boat. As Nigel climbed onto The Ancient Mariner, the Tylosaurus family swam off.

During the night, whilst Nigel and co. were sleeping, a larger family of Tylosaurus was detected by The Ancient Mariner's sonar system. They then attacked the boat.

List of appearancesEdit

Palaeontological inaccuraciesEdit

  • Tylosaurus, as well as all other mosasaurs, had a bi-lobed fluke like a shark rather than an eel-shaped tail.
  • A discovery in 2014 revealed that all mosasaurs was similar in colour to modern leatherback turtles.
