Noasaurus ("Northwestern Argentina lizard") is the name given to a carnivorous dinosaur genus of the late Campanian-Maastrichtian (Late Cretaceous). It was a small (less than eight feet long) theropod, specifically a ceratosaur, discovered by Jaime Powell and José Bonaparte from the Lecho Formation of Salta Province, Argentina, dating to the late Cretaceous period (early Maastrichtian stage, about 70 Ma ago).
It was a close relative of the larger abelisaurids; they are both derived from the same basal abelisauroid ancestor. While originally reported to have a raptorial 'sickle claw' on the foot similar to the claws of the more advanced dromaeosaurids, subsequent studies showed that the claw actually came from the hand.1
The type species, Noasaurus leali, was described by Bonaparte and Powell in 1980.
