EL REGISTRO DE MYLODON OWEN, 1840 (MAMMALIA, TARDIGRADA) EN EL PLEISTOCENO DEL SUR DE LA PROVINCIA DE BUENOS AIRES. COMENTARIOS SOBRE LA DISTRIBUCIÓN DE LOS "SEDIMENTOS PAMPEANOS"
Abstract"Remains of Mylodon (Mammalia, Tardigrada,Mylodontidae), recovered at Faro Segunda Barranca, Patagones county, were studied. The bearing sediments are brown reddish sandy silts, with volcanic and carbonate pebbles up to 1cm diameter. Some authors include this unit as a facies of the Miocene-Pliocene Río Negro Formation, while others refer it, with doubts, to the Pleistocene. The fossiliferous beds are closely similar to the "pampean sediments" that crop out in areas located to the north. The record of Mylodon confirms that the bearing sediments are Pleistocene in age and extends the distribution of the "pampean sediments" southwards."
