TheAltiplano formed a broad Cenozoic inverted sedimentary basin (>200 km wide) withup to 8 km of fluvio-lacustrinefilling in various sub-basins. This work is focused on the Corque basin whichrecorded evolution of the centralAltiplano and Neotropical terrestrial mammalian assemblages during the late Neogene. Indeed, this area isinferred to have experienced a rise from ∼1,500 to 4,000 m, between ∼10 and 6 Ma. Paleoclimates rapidly changed from warm climate at 10 Ma, with a mean annualtemperature (MAT) ~20°C, to the currenthighland climate (MAT ~8-9°C).
