One of the oldest known predatory dinosaurs, Herrerasaurus ischigualastensis stalked the Late Triassic of Argentina some 230 million years ago. About 6 meters long and 350 kilograms, this bipedal carnivore had a specialized sliding joint in its lower jaw that helped it grip struggling prey. Osvaldo Reig described it in 1963 from the Ischigualasto Formation, one of the richest windows into the earliest dinosaurs. Its exact place in the dinosaur family tree has been debated, but most analyses treat it as an early member of the lizard-hipped saurischians, close to the base of the lineage that later produced the great theropods and sauropods.
Herrerasaurus was one of the earliest known dinosaurs, from the Late Triassic. It was a bipedal predator with a flexible lower jaw joint. Its placement in dinosaur classification has been debated, but most analyses place it as an temprano saurischian.
