Epanterias
''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''. This genus is based on what is now AMNH 5767, parts of three vertebrae, a coracoid, and a metatarsal. Although Cope thought it was a sauropod,〔 it was later shown to be a theropod.〔 Gregory S. Paul reassessed the material as pertaining to a large species of ''Allosaurus'' in 1988 (which he classified as ''Allosaurus amplexus''). Other authors have gone further and considered ''E. amplexus'' as simply a large individual of ''Allosaurus fragilis''. 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''.〔Paul, G.S. and Carpenter, K. (2010).
