About Staurikosaurus
What it was like
Staurikosaurus was one of the earliest dinosaurs, a slim two-legged predator about 2 meters (7 feet) long. It belonged to the herrerasaurids, a family of early hunters with sharp, curved teeth and a long tail for balance.
Its world
It lived in the Late Triassic in what is now Brazil. Its bones come from the Santa Maria Formation, one of the richest sources of early dinosaurs. Other early dinosaurs from these rocks include the small plant eater Saturnalia and the predator Gnathovorax.
How it was found
Colbert named Staurikosaurus in 1970. The type species is Staurikosaurus pricei. Its name comes from a star pattern seen only from the Southern Hemisphere, and it was one of the first Triassic dinosaurs described from South America.
