A giant fossil sea monster found in the Arctic had such a ferocious bite it would have been able to crush a 4x4 car, say researchers.
Nicknamed Predator X, the reptile is thought to have roamed oceans about 147 million years ago, with jaws even more powerful than a Tyrannosaurus Rex.
Researchers, who discovered part of the creature's skull last summer, think it belongs to a new species of pliosaur – a group of large, short-necked reptiles that lived at the time of the dinosaurs.
But even by their standards, this sea monster's size has amazed scientists.
Its estimated length of 15 metres, or 1.5 school busses, is much bigger than another large pliosaur nicknamed The Monster, which was also uncovered in the Arctic archipelago of Svalbard in 2007.
