Its fossils, consisting of tail vertebrae, chevrons, ribs, and limb bones, were found in the late Turonian-early Coniacian-age (~89 million years old) Portezuelo Formation of the Neuquén Group. The type species, described by González Riga et al. in 2008, is M. florenciae. DescriptionDescribed as a robust sauropod, it was initially described as being closely related to Ligabuesaurus and Phuwiangosaurus, and Mannion et al. (2013) more precisely recovered it as a member of Somphospondyli.[1][2] The cladistic analysis of Patagotitan recovered Malarguesaurus as a close relative of the Asian Ruyangosaurus.[3] Like other sauropods, Malarguesaurus would have been a large quadrupedal herbivore.[4] Malarguesaurus is the second sauropod dinosaur discovered in Mendoza Province; the first is Mendozasaurus neguyelap.[5] References1. ^{{cite journal |last=González Riga |first=Bernardo J. |author2=Previtera, Elena |author3= Pirrone, Cecilia A. |year=2008 |title=Malarguesaurus florenciae gen. et sp. nov., a new titanosauriform (Dinosauria, Sauropoda) from the Upper Cretaceous of Mendoza, Argentina |journal=Cretaceous Research |volume=30 |issue=1 |pages= 135–148|doi=10.1016/j.cretres.2008.06.006}} 2. ^P.
