Saurophaganax was a genus of Allosaurus dinosaur from the Late Jurassic about 151 million years ago. It was discovered in Oklahoma, United States. Paleontologists considered this large, ferocious, carnivorous dinosaur to be most likely a giant species of Allosaurus.
To survive, Saurophaganax targeted juveniles of these huge herbivorous dinosaurs and had supplemented its diet with occasional portions of other Theropods such as Ornitholestes and Ceratosaurus.
Saurophaganax was large for a Jurassic theropod at around thirteen meters long, comparable to Tyrannosaurus. It was a dominant predator during its time and had to eat an enormous amount of food to provide energy for its metabolic needs. It probably included giant sauropods such as Amphicoelias, Sauroposeidon, Diplodocus, Apatosaurus, and the ornithopod Camptosaurus. There is no evidence to show whether Saurophaganax hunted alone or in groups or herds.
Saurophaganax comes from the Greek word σαυρος, sauros, "lizard", φάγειν, phagein, "to eat", with the compound meaning of "eating lizard".
Saurophaganax was large for a Jurassic theropod at about thirteen meters long comparable to Tyrannosaurus or even larger, making it one of the longest and largest carnivores.
Allosaurus and Saurophaganax were closely related; it has been described as their genus or as a species of Allosaurus: Allosaurus Maximus. It lived during the same epoch and coexisted with the same dinosaur fauna.
To survive, Saurophaganax targeted juveniles of these huge herbivorous dinosaurs and may have supplemented its diet with occasional portions of other theropods such as Ornitholestes and Ceratosaurus.
