a carnivorous noasaurid ceratosaurian dinosaur from the Late Cretaceous of Argentina.
Northwestern Argentina lizard
Bonaparte & Powell (1980
(Leal's Northwestern Argentina lizard)Etymology
is derived from an abbreviation of "noroeste Argentina" (a Spanish term meaning "North Western Argentina", the region including Salta Province where its remains were found), and the Greek "sauros" (lizard). The species epithet
(LEE-uh-lye), honors Don Fidel Leal, owner of the property on which the fossils were found. Coincidently, one of the technicians from the Paleontology Section of the Instituto Miguel Lillo who cleaned and prepared the remains is namesake J. C. Leal.
The remains of Noasaurus
were discovered in the Lecho Formation at El Brete, Salta Province, Northwest Argentina, by a team led by José Bonaparte between 1975 and 1977.
(PVL 4061) consists of a skull and vertebrae.
