NUEVOS REGISTROS DE MAMÍFEROS DEL PLEISTOCENO TARDÍO (MIS 5) EN EL SUR DE LA MESOPOTAMIA ARGENTINA

Abstract

. NEW RECORDS OF LATE PLEISTOCENE (MIS 5) MAMMALS IN SOUTHERN ARGENTINIAN MESOPOTAMIA. New records of mammals from the Late Pleistocene of the province of Entre Ríos are presented in this contribution. The fossils come from the Salto Ander Egg Formation, a unit which is deposited in the fluvial valleys of the southwest of Entre Ríos and dated between 120 ka and 60 ka by OSL. It is interpreted that the formation sequences were accumulated during MIS 5. The paleontological content of the unit constitutes the record that best characterizes the beginning of the Late Pleistocene for South America and the MIS 5e-MIS 5c transition. In this work 12 taxa are described: cf. Ozotoceros bezoarticus (Cervidae), Morenelaphus cf. brachyceros (Cervidae), Hemiauchenia paradoxa (Camelidae),
