Saurophaganax was a very large Morrison allosaurid. The maximum size of S. maximus has been estimated at anywhere from 10.5 metres (34 ft)^[2] to 13 m (43 ft) in length,^[3] and around 3 tonnes (3.0 long tons; 3.3 short tons) in weight.^[2] This means it was perhaps similar in size to Tyrannosaurus or Carcharodontosaurus.

Some paleontologists think it is a species of Allosaurus (Allosaurus maximus). It has also been described as a separate genus.^[4] The most recent review of basal tetanurans accepted Saurophaganax as a distinct genus.^[5] New possible Saurophaganax material from New Mexico may clear up the status of the genus.
