Saurophaganax (meaning "lord of lizard-eaters") is an extinct genus of allosaurid theropod dinosaur that lived in Oklahoma, USA during the Late Jurassic period around 151 million years ago. Some scientists describe Saurophaganax as a large species of Allosaurus (A. maximus). It was the largest predator of the Jurassic period, with the most optimistic estimates reaching 14 meters (46 feet) in length.
