The Norwegian Monster

The Norwegian researchers discovered remains of a total of 28 plesiosaurs and ichthyosaurs -- top marine predators when dinosaurs dominated on land -- at a site on the island of Spitsbergen, about 1,300 km (800 miles) from the North Pole.

"One of them was this gigantic monster, with vertebrae the size of dinner plates and teeth the size of cucumbers," Joern Hurum, an assistant professor at the University of Oslo, told Reuters on Thursday.

"We believe the skeleton is intact and that it's about 10 meters (33 feet) long," he told Reuters of the pliosaur, a type of plesiosaur with a short neck and massive skull. The team dubbed the specimen "The Monster."
