Saurophaganax was a large carnivorous dinosaur that lived during the late Jurassic period, approximately 150 million years ago. It belonged to the group of theropods, which are known for their bipedal stance and sharp teeth. Fossils of Saurophaganax have been found primarily in North America, indicating it was a dominant predator in its ecosystem. This dinosaur could reach lengths of up to 30 feet and was characterized by its long legs and powerful jaws. Saurophaganax is often compared to other large theropods like Allosaurus, as they shared similar habitats and prey. Its name means "lizard-eating master," reflecting its role as a top predator of its time.
