Epanterias is a genus of theropod dinosaur from the Kimmeridgian-Tithonian-age Upper Jurassic Morrison Formation of 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 (Allosaurus amplexus),[3] and other authors have gone further with the comparison and considered E. amplexus simply a large individual of Allosaurus fragilis.[4] This genus is known for its size, estimated as measuring 12.1 meters in length (39.7 ft) — nearly as large as Tyrannosaurus.[5]
