Edgarosaurus

Edgarosaurus is a genus of polycotylid plesiosaur from the Thermopolis Shale, containing one species, E. muddi.[1] The type specimen was found in Early Cretaceous (late Albian) rocks in the state of Montana in the United States.[1] At the time, this location was covered by part of the Western Interior Seaway. Edgarosaurus was one of the first polycotylids that evolved to become native to the Western Interior Seaway.
