Resumen:
In ?La Invernanda-Cerro Overo? area (Rincón de los Sauces, Neuquén Province, Argentina) outcrop continental sediments of Bajo de la Carpa Formation (Santonian, Upper Cretaceous). This area has shown a great diversity of vertebrates including dinosaurs, such as the abelisaurid theropod Viavenator exxoni, the titanosaur sauropod Overosaurus paradasorum, the ornithopod Mahuidacursor lipanglef, and crocodyliforms, such as the peirosaurid Kinesuchus overoi; beside turtles, fresh water fishes, dinosaur eggs, and fragments of petrified wood (being the flora in general unknown for this formation). As a result of the field work carried out in 2019, a small titanosaur specimen (MAU-Pv-CO-660) partially articulated and integrated by axial and appendicular skeleton, two theropod specimens (Megaraptoridae indet., MAU-Pv-CO-659 and Abelisauridae indet., MAU-Pv-CO-661) preserving craneal, axial and appendicular bones, and isolated ornithopod bones. Remains isolate of other vertebrates have also found as turtle shells, fish teeth and osteoderms, teeth and mandible fragment of crocodyliforms. This great diversity of the fossil record allows carrying out multidisciplinary studies, including ?among others- paleoecological, sedimentological, taphonomic, and paleobiogeographic aspects. This integral approach of vertebrateand plant associations will allow a paleoenviromental and paleobiological reconstruction of the Cretaceous ecosystem innorthern Patagonia, around 85 Million years ago.
