Elasmosaurus (name meaning "Plated Lizard") is a genus of large plesiosaur that originated during the Late Cretaceous period related to Liopleurodon and Cryptoclidus. Reached 13-15 meters long, despite much of its length was made of its neck, which consisted of 75 vertebra, Elasmosaurus was the largest of the Plesiosaurs.

FactsEdit

Era & DiscoveryEdit

Elasmosaurus lived in the waters of the Late Cretaceous period 75-65 million years ago. The first specimen of Elasmosaurus was discovered in 1867 near Fort Wallace, Kansas, and was sent to the American paleontologist Edward Drinker Cope.

Physical AttributesEdit

Elasmosaurus was the largest plesiosaur ever to roam the seas. They measured 9-15 meters long and weighed as much 10 tons, making them larger than their earlier Jurassic cousins Cryptoclidus, arguably the largest member of the Plesiosaurs.

Behavior & TraitsEdit

Elasmosaurus lived in huge numbers and was some of the most exciting reptiles ever discovered. They could save energy like dolphins do. Their small heads on their long necks were a way to deceive prey. Fish would have been frightened by their big bodies, but what the Elasmosaurus did was, like their ancestors Cryptoclidus, Elsamosaurus could sneak those heads right into the middle a shoal, and then strike.
