TOOTH OF A MOSASAUR

90 million years old (Cretaceous Period)

Khouribga, Morocco

At the top of the food chain in the late Cretaceous seas were mosasaurs, giant marine reptiles sometimes over ten metres long with a long lizard-like body and tail, paddle-like limbs and heavy jaws armed with sharp, conical teeth. They were active predators and probably preyed on other mosasaurs, fish, and sharks.

Mosasaurs lived their whole lives in the sea. They were not dinosaurs, but they became extinct at the same time as the dinosaurs about 65 million years ago.
