A “more (greater) saurian”) from Middle-Late Jurassic and Creataceous Europe. It was not a dinosaur. Named by British anatomist Sir Richard Owen in 1841.

"Sea Rex Pliosaurs" apparently were as big as buses with teeth the size of bananas.

• They probably lay in wait and lunged at their prey.
• They lived in the Jurassic period but were marine reptiles, and again, not dinosaurs.
• The largest known pliosaur fossil, a 50-foot-long, 150-million-year-old specimen was found by University of Oslo researchers.
• It was found in a hillside of shale on the high Arctic island of Spitsbergen, 400 miles from Norway's coast.
