Campamento Vespucio, una nueva localidad con mamíferos pleistocenos en la provincia de Salta, Argentina

Abstract

In this contribution a new locality with Pleistocene fossil mammals is presented. The materials come from the Quebrada del Aguay, Campamento Vespucio, General Mosconi, Salta province, Argentina; they are tentatively assigned to the Urundel Fm. (late Pleistocene). The palaeofaunistic association includes six taxa: Xenarthra Glyptodontidae: Glyptodon sp. and Panochthidae: Neosclerocalyptus sp.; Tardigrada Megatheriinae: gen. et. sp. indet.; Proboscidea Gomphotheriidae: Stegomastodon sp; Notoungulata Toxodontidae: Toxodon sp. Perissodactyla Equidae: Equus (Amerhippus) sp. This set of Pleistocene mammals presents a wide latitudinal distribution in South America. Some of them (e.g. Neosclerocalyptus) are congruent with arid/semiarid, cold conditions and open environments. In this scenario, this contribution improves the knowledge that we have in northern part of Argentina, very scarce compared with respect to that of the Pampean region.
