Noasaurus

Noasaurus leali

Noasaurus ("Northwestern Argentina lizard") is a genus of ceratosaurian theropod dinosaur from the Maastrichtian (Late Cretaceous) of Argentina. The type and only species is N. leali. The fragmentary holotype specimen of Noasaurus, PVL 4061, consisting of a few cranial and postcranial bones, was discovered from strata from the Lecho Formation of Southern Salta in 1975 by a team led by José Fernando Bonaparte. When described by Bonaparte and in PhD student Jaime Powell in 1980, it was believed to be a coelurosaur theropod and assigned to a family of its own; this family, Noasauridae, still exists, though has been reassigned to Ceratosauria. Noasaurus was a fairly small theropod, with PVL 4061 measuring somewhere between 1.6–2 m (5.2–6.6 ft) in length
