Predator X
Predator X is a giant species of the pliosaur Pliosaurus funkei. It was discovered in 2006 by Norwegian scientist, Jørn Hurum. The skull was dug up in 2008 and told a lot about this animal.
The animal had an estimated bite force that was four times more powerful than that of Tyrannosaurus and 10 times more powerful than any modern predators like the saltwater crocodile and the great white shark.
This creature measured 49 feet long and weighed 99,000 pounds (49.5 tons). It lived about 147 million years ago and its remains were discovered in the Arctic.
