Malarguesaurus

Malarguesaurus (meaning "Malargue lizard" after the Malargüe Department of Mendonza Province) is a genus of titanosauriform sauropod dinosaur from the Late Cretaceous of Mendoza Province, Argentina. Its fossils, consisting of tail vertebrae, chevrons, ribs, and limb bones, were found in the early to middle Coniacian-aged (~89 million years old) Los Bastos Formation of the Neuquén Group. The type species, described by González Riga "et al." in 2008, is "M. florenciae".
Description.
Described 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. The cladistic analysis of "Patagotitan" recovered "Malarguesaurus" as a close relative of the Asian "Ruyangosaurus".
Like other sauropods, "Malarguesaurus" would have been a large quadrupedal herbivore. "Malarguesaurus" is the second sauropod dinosaur discovered in Mendoza Province; the first is "Mendozasaurus neguyelap".
