 Daniel Chure 's work on Morrison allosaurid remains has been responsible , directly or indirectly , for " A. jimmadseni " and A. maximus . " A. jimmadseni " is the proposed name for a new species of Morrison allosaur , based on a nearly complete skeleton and skull . A. sp . 2 , as it is also known , differs from A. fragilis in several anatomical details including a jugal or cheekbone with a straight lower margin , and is also found only in the Salt Wash Member of the Morrison Formation , with A. fragilis only present in the higher Brushy Basin Member . A. maximus was coined by David K. Smith for Chure 's Saurophaganax maximus , a taxon created by Chure in 1995 for giant allosaurid remains from the Morrison of Oklahoma . These remains had been known as Saurophagus , but that name was already in use , leading Chure to propose a substitute . Smith , in his 1998 analysis of variation , concluded that S. maximus was not different enough from Allosaurus to be a separate genus , but did warrant its own species , A. maximus . This reassignment was rejected in the most recent review of basal tetanurans .
