‘Monster’ fossil find in Arctic from the BBC covers a massive “treasure trove” of plesiosaurs and ichthyosaurs found on Spitsbergen, a large island between Norway and the North Pole. A giant plesiosaur fossil has been nicknamed “The Monster” as it is so large, 8 meters long. They also found an ichthyosaur tooth embedded in the neck of a plesiosaur, suggesting an attack. There are six ichthyosaur fossils in all, 21 plesiosaur ones.
