Restos de Hippidion y Equus (Amerhippus) procedentes de las barrancas de San Lorenzo, Pleistoceno Tardío (provincia de Santa Fé, Argentina

Abstract

Los mamíferos fósiles de la Provincia de Santa Fé (Argentina) son escasamente conocidos. En este trabajo, se describen los restos mejor conservados de équidos (Mammalia, Perissodactyla) encontrados en los niveles pleistocenos aflorantes a lo largo del Río Paraná, cerca de la ciudad de San Lorenzo. El estudio comparativo con otros caballos provenientes de distintas localidades de América del Sur, en su mayoría argentinas y brasileñas, permite identificarlos como Equus (Amerhippus) neogeus e Hippidion principale. La sección estratigráfica analizada no cuenta con dataciones radiométricas o estudios paleomagnéticos que permitan calibrar con cierta precisión la edad de los depósitos portadores de équidos. En consecuencia, en base a correlaciones estratigráficas, los restos hallados estarían situados en un lapso que se extiende desde 128 ka (inicio del Pleistoceno Superior, estadio isotópico 5e) como edad máxima hasta momentos anteriores al comienzo del estadio isotópico 2e (28 ka).
