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.

The holotype (which is currently the only known specimen) consists of the skull, neck, parts of the spine and the left front flipper.^[1]
