Resumen:
Chucarosaurus diripienda gen. et sp. nov. is a new and large titanosaurian sauropod from the Neuquén BBasin, Rio Negro Province, Patagonia. The specimen was discovered in the Upper Late Cretaceous strata of the Huincul Formation (middle Cenomanian-lowerearly Turonian). It includes appendicular and relatively slender elements, with a femoral total length of about 1.9 m long. This taxon shows a unique combination of characters indicating that appendicular bones such as the femur, ischium and tibia, show a remarkable morphological variety, greater than previously described, and are morphologically informative as source of phylogenetic data. A cladistic phylogenetic analysis placed Chucarosaurus well nested within the Colossosauria clade, as a sister taxon of Notocolossus + (Lognkosauria).
