FUN FACTS

Mosasaurs cannot breathe underwater. However, it can hold its breath a long period of time, like a whale today can
Mosasaurs are deep-sea marine lizards, and NOT a fish
It spends most of its time in the deep waters, and only comes up to surface to breathe, or chase its prey
Has a second set of teeth in its upper palate that ensures any prey sliding down its throat will not be able to escape
Komodo dragon and monitor lizards are among the closest living relatives of mosasaurus
Has sideward facing eyes, which means it had poor stereoscopic vision
Poorly developed olfactory bulb (which helps process smells), this was a disadvantage compared to other sea creatures
Fossils been found worldwide including: northern Europe, eastern Europe, Russia, Turkey, the Middle East, northern Africa, Canada, South America, the United States, and islands of coastal Antarctica.

M. hoffmanni versus C. megalodon!

These animals were both apex predators of the sea. But they would have never met, as they were separated by 50 million years. After the Cretaceous period the Mosasaurus went extinct, this allowed massive sharks like megalodon to evolve to fill the void left behind. Both creatures were fairly the same size in length.

But if both were to live in the same time, who would've been the better predator?
