Elasmosaurus

To Monsters

As captioned in Life of a Fossil Hunter Fig. 23.—The Snake-necked Elasmosaurus, Elasmosaurus platyurus.
Discovered in the Niobrara Group of the Cretaceous. Restoration by Osborn and Knight. (From painting in American Museum of Natural History.) 1909(1909) Fig. 23 (opposite page 123) of The Life of a Fossil Hunter (New York, 1909) by Charles H. Sternberg (1850–1943). Scanned by the Internet Archive. Charles R. Knight (1874–1953)

Has a thick, ovoid body with fins instead of legs and a long, snaky tail and neck. Though it resides primarily in the water, an elasmosaurus only breathes air. An elasmosaurus has a total length of some 30 feet, including a tail half as long as its entire body, and weighs about 5,000 pounds. Observers who see only its head or tail might easily mistake it for a massive snake.
