“The Mosasaurus was thought to have hunted near the surface of the water, where it preyed on anything it could sink its teeth into, including turtles, large fish, even smaller mosasaurs”


The Mosasaurus was terrorizing the seas during the Mesozoic era (70-66 million years ago) and is believed to be one of the largest carnivorous aquatic lizards to have ever existed.

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.

Feeding on its own species would mean that the Mosasaurus were not hunting in packs as they were lone hunters fighting for territory with their own kind.

The Mosasaurus was able to eat very large objects due to a very unusual double-hinged jaw. This basically allowed the Mosasaurus to dislocate its jaw when biting on something very big just like the Python snake.

Their teeth were not great for slicing but they were perfect to grip and rip to shreds its victims. 

Despite its size, the Mosasaurus was believed to have been a pretty fast swimmer which makes it much more terrifying and dangerous than the Plesiosaurs.
