The most fearsome sea monster the world has ever seen has been found buried in the Arctic.

Dubbed “Predator X”, the massive pliosaur was fifty feet long and weighed 45 tons.

It had massive jaws with a bite force of 33,000 pounds – ten times the force of any animal alive today, including the Great White Shark.

Every tooth in its massive jaw was a foot long and Predator X clamped its victims with four times the force of T-Rex.

Predator X, which patrolled the oceans 147 millions years ago, was found buried in the remote Arctic near Svalbard by a team of scientists led by Dr Jorn Hurum of the Natural History Museum, University of Oslo.

They found another headline-making pliosaur – dubbed The Monster – two years ago and they were just leaving when when they spotted some more bones.

They marked the spot with a GPS reading and returned a year later to find the head of an even bigger sea giant – Predator X.

After a two week dig they found the skull of the buried in the frozen ground.

Its size and body and hunting skills all point to it being the most dangerous predator ever to patrol the world’s oceans.

The bone linking its skull to its back is six inches in diameter making its skull twice the size of a T-Rex dinosaur.

The team also found 20,000 bone fragments which are being glued together to reconstruct the monster at the Natural History Museum, University of Oslo.

Predator X had four flippers to propel its massive body through the water.

Scientists used a flippered robot and did tests in a wind tunnel to see how it swam, calculating it would only need two flippers.
