British authorities say the fossilized skull of a giant sea monster has been found off England's southern coast. The fossil came from a pliosaur, a ferocious predator that lived in the oceans 150 million years ago. The skull was discovered in Dorset by a collector and measures 2.4 meters (8 feet) in length. The discovery was announced Tuesday. Scientists believe the creature would have been about 16 meters (52 feet) long. David Martill, a paleontologist from the University of Portsmouth, says pliosaurs had short necks and huge, crocodile-like heads with powerful jaws and a set of razor-sharp teeth. He said they used paddle-like limbs to propel their bodies through the water and were generally carnivores.
