Staurikosaurus is a genus of herrerasaurid dinosaur from the Late Triassic of Brazil, found in Paleorrota Geopark.

Colbert (1970) described Staurikosaurus as a small and agile, bipedal predator. Staurikosaurus lived during the late-Carnian and early-Norian stage, of the late Triassic Period, 225 million years ago – which makes it one of the earliest dinosaurs known. At 2.25 metres (7.4 ft) long, 80 centimetres tall (31 in), and weighing 30 kilograms(66 lb), Staurikosaurus was small in comparison to later theropods like Megalosaurus. The type specimen has long but relatively slender limb bones.
