Zupaysaurus ("ZOO-pay-SAWR-us") is a genus of early theropod dinosaur living during the Rhaetian stage of the Late Triassic to Hettangian stage of the Early Jurassic of what is now Argentina. Although a full skeleton has not yet been discovered, Zupaysaurus can be considered a bipedal predator, up to 4 meters (13 ft) long. It may have had two parallel crests running the length of its snout.
