mi) southwest of Villa El Chocón, Picún Leufú Department, Neuquén Province, Patagonia, Argentina. The sediments belong to the Río Limay Subgroup, in Lohan Cura Formation, at Cerro Aguada del León. These beds appear to date from the Aptian-Albian interval, although these fossils were later named Comahuesaurus. Classification The describing authors in 2004 assigned Limaysaurus to the family Rebbachisauridae. The rebbachisaurids are a basal clade within the Diplodocimorpha, and their remains have been found in Cretaceous-age rocks in Europe, South America, and Africa. A cladistic analysis of macronarian sauropods (Salgado et al., 2004) demonstrated close affinities between Limaysaurus, the African genera Rebbachisaurus and Nigersaurus, and the South American genera Rayososaurus and Cathartesaura.
