Elasmosaurus (name meaning "Thin-Plated Lizard") is a genus of plesiosaur that originated during the Late Cretaceous period in what is now North America. Distinguishable by its small head, long and slender neck, broad turtle-like body, a short tail, and two pairs of large, elongated paddles, Elasmosaurus is the largest and most famous plesiosaur.
In the Series 2 finale "Death of a Dynasty: To Hell... And Back", a pod of Elasmosarus were brought to the park from Late Cretaceous Montana 65 million years ago. They reside in the Marine Enclosure.
