Megalneusaurus was a giant marine reptile that swam in the shallow Sundance Sea during the Late Jurassic. It was one of the biggest predators in North America at that time, with four flippers and a big head.1

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

Fossil stomach contents include tiny hooks from squid-like animals and bits of fish bones.1 2

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

?How big was Megalneusaurus?

Megalneusaurus was about 7 to 9 meters (23 to 30 feet) long. Some estimates say it could reach around 13 meters (43 feet).1

?What did Megalneusaurus eat?

It ate squid-like animals and fish, based on hooklets and fish bones found in its stomach. It may also have eaten other plesiosaurs.1 2

?Could Megalneusaurus live in cold water?

Yes. A specimen found in Alaska shows it could live in colder waters, where there were fewer animals.1

?Was Megalneusaurus a dinosaur?

No, it was a marine reptile called a pliosaur, not a dinosaur. It lived in the sea.1

Atosɛm sɛefoɔ

Atosɛm: Some people think Megalneusaurus was a dinosaur.

Nokorɛ: It was a plesiosaur, a marine reptile, not a dinosaur.1
