Abstract. A new titanosaur sauropod from the Upper Cretaceous of Neuquén is described, Choconsaurus baileywillisi gen. et sp. nov. The species is represented by a nearly complete series of dorsal vertebrae as well as other parts of the skeleton. The material comes from the locality of Villa El Chocón and stratigraphically from the Huincul Formation, whose age has been estimated as upper Cenomanian. The new taxon presents many autapomorphic features, including the presence of a small notch on…

A good part of the postcranial skeleton of an Albian-Cenomanian primitive titanosaurid from Patagonia is described and discussed, and it is argued that the latter were endemic and very diversified, representing the major herbivorous group of the Late Cretaceous fauna of Gondwana.

The new mid-sized sauropod is related to Rebbachisaurus and Limaysaurus because of the presence of several synapomorphies, which support its inclusion in a separate clade of basal Diplodocoidea, the ReBBachisauridae.
