Epanterias(Allosaurus) Amplexus vs Carcharodontosaurus Saharicus

Epanterias

Epanterias is a genus of allosaurid from the Jurassic period of Colorado. It was described by Edward Drinker Cope in 1878. The type speciesis Epanterias amplexus. This genus is based on AMNH 5767, parts of three vertebrate, 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". 

Carcharodontosaurus 

Carcharodontosaurusis a genus of carcharodontosaurid  during the  mid- Cretaceous period.It is currently known to include two species, C.saharicus andC.iguidensis, which were among the larger theropods, as large as or slightly bigger than Tyrannosaurus and possibly slightly larger than Giganotosaurus, but not quite as large as Spinosaurus. At the time being, it appears C.Saharicus is larger then C.Iguidensis.
