"Rare and Complete Pliosaur Skull Unearthed in U.K."

The skull of a pliosaur, an ancient sea monster, has been discovered on the U.K.'s southern Jurassic Coast. The fossilized skull, which still has 130 razor-sharp teeth, is one of the most complete pliosaur skulls ever found. The pliosaur, a marine reptile that lived around 150 million years ago, was about 10 to 12 yards long and had extremely strong jaw muscles. The discovery will provide valuable insights into the life and behavior of these prehistoric creatures.
