Epanteriasis adubiousgenusoftheropoddinosaurfrom theTithonianageUpper JurassicupperMorrison Formationof Garden Park,Colorado.It was described byEdward Drinker Copein 1878. Thetype speciesisEpanterias amplexus.[1]This genus isbased onwhat is nowAMNH5767, parts of threevertebrae,acoracoid,and ametatarsal.[2]Although Cope thought it was asauropod,[1]it was later shown to be a theropod.[2]Gregory S. Paulreassessed the material as pertaining to a largespeciesofAllosaurusin 1988 (which he classified asAllosaurus amplexus).[3]Other authors have gone further and consideredE. amplexusas simply a large individual ofAllosaurus fragilis.[4]In 2010, Gregory S. Paul andKenneth Carpenternoted that theE. amplexusspecimen comes from higher in the Morrison Formation than the type specimen ofAllosaurus fragilis,and is therefore "probably a different taxon". They also considered its holotype specimen not diagnostic and classified it as anomen dubium.[5]
Etymology
[edit]Thegeneric epithettranslates to "buttressed" in Greek, in reference to the vertebrae. The wordamplexusrefers to thecopulatoryposition ofamphibiansin which males clasp their mates. Therefore, thespecific epithetmeans "clasping buttressed vertebrae" inLatin.
