Megalneusaurus was one of the largest pliosaurs in North America, measuring about 7 to 9 meters (23 to 30 feet) long.1
Its back flippers were bigger than its front flippers, which is unusual for plesiosaurs.1
It lived in the Sundance Sea, a shallow sea that covered parts of North America during the Jurassic.1
Scientists think it was an ambush predator, waiting to surprise its prey.1
A specimen from Alaska suggests it could also live in colder waters.1
