1

Megalneusaurus was one of the largest pliosaurs in North America, measuring about 7 to 9 meters (23 to 30 feet) long.1

2

Its back flippers were bigger than its front flippers, which is unusual for plesiosaurs.1

3

Fossil stomach contents include tiny hooks from squid-like animals and bits of fish bones.12

4

It lived in the Sundance Sea, a shallow sea that covered parts of North America during the Jurassic.1

5

Scientists think it was an ambush predator, waiting to surprise its prey.1

Wilbur Clinton Knight found and described the first fossils in 1895, near Ervay, Wyoming. He first called it Cimoliosaurus rex, then gave it its own genus name in 1898.12
ገና ዘከራኽር
Scientists debate whether Megalneusaurus is a valid genus because many of the original fossils were lost.1
