Epanterias vs Saurophaganax

[Super Communist]

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, 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]

Saurophaganax ("lizard-eating master") is a genus of allosaurid dinosaur from the Morrison Formation of Late Jurassic Oklahoma (latest Kimmeridgian age, about 151 million years ago).[1] Some paleontologists consider it to be a species of Allosaurus (A. maximus). Saurophaganax represents a very large (13 metres (43 ft) long)[2] Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons.[3]

[Tyrannosaurus]

I think they're both Allosaurus, Saurophaganax might be a seperate species but Epanterias has no known distinctions except size from A. fragilis. I think Saurophaganax is the bigger of the two, but Epanterias is based on fragmentary remains, so it's size is an estimation.

50/50?

[Tyrannosaurus]

Epanterias is estimated at 11 meters, Saurophaganax was 13 meters. So probably Saurophaganax.

[Anomonyous]

Were there any differences besides length?

[Tyrannosaurus]

Yes, my encyclopedia says that Saurophaganax differs from A. fragilus in certain features on the skull and spine, as well as the major size disparity. As of 2000 though nobody had tested the Epanterias fossils for these features.

[Godzillasaurus]

Both of these animals were allosaurids. Because of this, the bigger animal wins. We're they different? Heck yea! But they were still both very similar in terms of weaponry, build, and specialization (which animals they hunted). I have heard some sources claim epanterias to be bigger, while others claim saurophoganax to be bigger.

[Dinopithecus]

Epanterias seems to be 12 meters while Saurophaganax 11 meters, thus Epanterias would likely weigh more.

[Carcharadontosaurus]

Epanterias wins due to size advantage, saurophaganax was really probably only like 11 m long.

[Memememememme]

Saurophaganax would win because it was bigger

[theking]

Epanterias was 12 meters and Saurophaganax was 13 meters...Saurophaganax wins
