Paleontology of the Saldeño Formation (Maastrichtian), High Cordillera of Mendoza, Argentina

Mostrar todas las versiones(2)

The carbonatic and silicoclastic Saldeño Formation crops-out in the High Andes of Mendoza, about 33° 33′ - 34° 25′ S lat., near the border with Chile. Crustaceans, fishes, gastropods, ostracods and pelecypods are mentioned in the formation for the first time. These fossils provide information that e...
