Discosaurus is an extinct genus of plesiosaur from the Santonian of Alabama and Mississippi.1 One species is known, which is D. vestutus.
Discovery and naming
The holotype, eleven vertebrae, was discovered by Joseph Jones in Alabama and Mississippi, and was named and described as Discosaurus vestutus by Leidy (1851).2 Two more specimens from New Jersey were described and were later re-classified as belonging to Cimoliasaurus magnus by Leidy (1870b).3
Leidy (1870b) later argued that Discosaurus was the same animal as Elasmosaurus.3
