It has been described as its own genus, [4] or as a species of Allosaurus: Allosaurus maximus. [7] A review of basal tetanurans in 2004 and Carrano et al.'s comprehensive 2012 analysis of Tetanurae accepted Saurophaganax as a distinct genus. [8] [9] Possible Saurophaganax material from New Mexico may clear up the status of the genus. [10]
