New Titanosauria (Dinosauria, Sauropoda) remains from the Upper Cretaceous (Plottier Fm) of the southern Neuquén Basin (Patagonia, Argentina)
Purpose: New sauropod remains (MCF-PVPH-889, MCF-PVPH-899, and MCF-PVPH-900) collected from the Plottier Fm (Coniacian–Santonian) in the south-west of the Neuquén Basin, are here reported. The materials proceed from a fluvial outcrop composed by siltstone and fine sandstone, whose fossil record is k...

MCF-PVPH-889 and MCF-PVPH-900 share some features with other titanosaurian taxa (e.g., a femur with medial deflection of the proximal end and elliptical mid-shaft cross-section, a fibula with slightly sigmoidal shaft and well-developed lateral tuberosity) like in Epachthosaurus and Antarctosaurus. However, the femur, with a poorly developed lateral bulge and a relatively low head, and a fibula, with a slender and nearly straight proximal third of the shaft, represent plesiomorphic conditions among titanosaurians. Conclusions: The new remains represent a new sauropod record from the Plottier Fm (Upper Cretaceous).
