A Big Monster

More than 147 million years ago, huge reptiles ruled the seas. Scientists at the University of Oslo Natural History Museum, in Norway, say that they have new findings about one of the largest predators ever to hunt on Earth.

The reptile is a pliosaur (ply-uh-sore). Scientists are calling the creature "Predator X." It was 50 feet long with 12-inch-long teeth. Its skull was at least twice as big as that of Tyrannosaurus rex.

Predator X was heavier and stronger than T. rex. "It weighed 45 tons, compared with T. rex, which weighed six to seven tons," Jorn Hurum told TFK. He led the expedition that dug the fossil up on a remote Norwegian island 800 miles from the North Pole.

Predator X could bite down with a force of 33,000 pounds. That's 10 times the bite force of any creature alive today!
