Halisaurus was a small mosasaur from the Cretaceous. This was a relative of the much larger Tylosaurus.

Physical appearance and biologyEdit

Behaviour and traitsEdit

Halisaurus was a small mosasaur. Like its relatives, it had a streamlined body with a powerful tail which propelled it through the water with tremendous speed. Halisaurus hunted small marine animals as well as the aquatic sea bird Hesperornis. This mosasaur mainly lived in coral reefs.

In Sea MonstersEdit

The Most Deadliest Sea EverEdit

A Halisaurus as well as several other predators including Xiphactinus and sharks hunted a colony of diving Hesperornis. In the frenzy, the attacking Halisaurus left the scene and went back to the coral reef it lived in.

Behind the scenesEdit

List of appearancesEdit

Palaeontological inaccuraciesEdit

  • Halisaurus as well as all the mosasaurs are now believed to have a bi-lobed fluke instead of an eel-like tail.
  • A discovery in 2014 revealed that all mosasaurs was similar in colour to modern leatherback turtles.
