Elasmosaurus
Pronounced: e-LAZ-mo-sawr-us
Literally, "thin plate lizard"
Elasmosaurus was one of the fish-eating Plesiosaurs that lived during the Cretatceous period, 70 million years ago. He was 50 feet long, weighed about 10 tons, and like the modern sea turtles, spent most of his life in the water.
