Epanterias is a dubious genus of theropod dinosaur from the Kimmeridgian-Tithonian-age Upper Jurassic upper Morrison Formation of Garden Park, Colorado. It was described by Edward Drinker Cope in 1878. The type species is Epanterias amplexus.[1] This genus is based on what is now AMNH 5767, parts of three vertebrae, a coracoid, and a metatarsal.[2] Although Cope thought it was a sauropod,[1] it was later shown to be a theropod.[2] Gregory S. Paul reassessed the material as pertaining to a large species of Allosaurus in 1988 (which he classified as Allosaurus amplexus).[3] Other authors have gone further and considered E. amplexus as simply a large individual of Allosaurus fragilis.[4] In 2010, Gregory S. Paul and Kenneth Carpenter noted that the E. amplexus specimen comes from higher in the Morrison Formation than the type specimen of Allosaurus fragilis, and is therefore "probably a different taxon". They also considered its holotype specimen not diagnostic and classified it as a nomen dubium.[5]
