Pitekunsaurus

Pitekunsaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Anacleto Formation of Neuquén, Argentina. It was described by L. Filippi and A. Garrido in 2008. The type species is "P. macayai". The generic name is derived from Mapudungun "pitekun", meaning "to discover", the epitheton honours the discoverer, oil company explorer Luis Macaya, who found the fossil in April 2004.
Classification.
"Pitekunsaurus" appears to be a genus of aeolosaurid, most closely related to the genera "Gondwanatitan" and "Aeolosaurus". Its braincase closely resembles that of the aeolosaurid "Muyelensaurus" as well as the titanosaurs "incertae sedis" "Vahiny" and "Jainosaurus". It cannot be compared to the more closely related "Aeolosaurus" and "Gondwanatitan" in this regard, as neither genus is known from cranial material.
