The Megalodon was around the same length as the Smilodon, but its body was significantly more powerful, and it had enormous jaws designed specifically for devouring whales and other large marine mammals. These were a group of large marine reptiles and were the dominant marine predators for millions of years up until the end of the Cretaceous period. They are distantly related to dinosaurs.

Most people know the Mosasaurus from the 2015 film Jurassic World, where it chomped down on its fair share of prey, including the mutant Indominus rex.

First, the mosasaur had to have died immediately after consuming their prey, before digestion obscured all traces of its shape. All these animals were victims of the catastrophic Chicxulub impact event, which wiped out every living thing in its vicinity and then brought about sudden and permanent changes in the climate. Why didn't the Indominus rex utilise her camouflage ability more often?

How did it survive all that time? Its tail was half the length of its body and was downward facing which may indicate it was a fast swimmer. It lived in oceans surrounding North America. It also had a bite force of 13K, one pound higher than the terrestrial predator Tyrannosaurus rex that lived in the same period as the Mosasaurus.

There's apparently no shortage of dinos (both flying and non) left on the island at the end of the film. Mosasaur facts! Fossil predators are often found with small bones in their bellies, and usually scientists interpret those bones as the remains of a prey item. Ecological Niche: Carnivorous sea mammal.

It meant they had an efficient system as like many carnivores their teeth were essential in catching their prey.
