In this paper we describe the only specimens of sauropod dinosaur known in the Rayoso Formation (Albian,Patagonia, Argentina). We found a partially articulated adult specimen and remains of two juveniles in the same site. The adult is represented by most of the skull, neck and much of tail articulated. The juvenile specimens retain much of the appendicular skeleton and scapula, high systematic importance. The morphological features of the teeth, caudal vertebrae and scapula place the collected specimens among the rebbachisaurids, though with clear differences with other taxa described for the Lower Cretaceous of Argentina, so it could be a new species.
