Hypsirhophus (often spelled Hypsirophus) is a dubious genus of stegosaurian dinosaurs. It contains a single species, Hypsirhophus discurus, which is known only from a fragmentary specimen. The fossil consists of partial vertebrae from the back, three from the tail, and a piece of rib.
The specimen was excavated from Edward Drinker Cope's Quarry 3 near the "Cope's Nipple" site in Garden Park, Colorado, near the very top of the late Jurassic Morrison Formation.[1] In 1878, Cope named the specimen Hypsirhophus discurus. Some later researchers have considered Hypsirhophus to be a synonym of Stegosaurus,[2] or as a nomen dubium,[3] though Ken Carpenter and Peter Galton have suggested that it is distinct based on differences in the vertebrae.[4]
