Herrerasaurus was one of the earliest dinosaurs. Its name means "Herrera's lizard", after the rancher who discovered the first specimen. All known fossils of this carnivore have been discovered in the Ischigualasto Formation of Carnian age (late Triassic according to the ICS, dated to 231.4 million years ago) in northwestern Argentina.[1] The type species, Herrerasaurus ischigualastensis, was described by Osvaldo Reig in 1963[2] and is the only species assigned to the genus. Ischisaurus and Frenguellisaurus are synonyms.
