| dc.description | Se da a conocer un conjunto de restos oseos de mamiferos pleistocenos provenientes de distintas localidades de la Provincia del Chaco, Argentina. El conjunto esta integrado por Glyptodon sp., Neosclerocalyptus cf. N. heusseri, Panochthus sp., Propraopus grandis, Megatherium cf. M. americanum, Megatherium sp., Scelidotherium cf. S. leptocephalum, Lestodon sp., Equus (Amerhippus) neogeus, Toxodon cf. T. gezi y Toxodon sp., Smilodon populator, Morenelaphus sp., Stegomastodon cf. S. platensis, Stegomastodon sp. La asociacion es referible al Bonaerense-Lujanense (Pleistoceno medio- Holoceno temprano). Desde el punto de vista paleozoogeografico muestra gran similitud con aquellas de igual antigüedad de la region pampeana, de la Provincia de Formosa, Paraguay y sudeste de Bolivia. Estas similitudes son atribuidas a una marcada homogeneidad ambiental. Por otro lado, una comparacion preliminar con la paleomastofauna de Chile indica algunas diferencias significativas, fundamentalmente con respecto a la region central, mientras que hacia el sur y norte se observan mayores similitudes con la paleofauna cuaternaria de Argentina. | es-ES |
| dc.description | In this paper, the authors report the remains of some taxa of Pleistocene mammals coming from Chaco Province, Argentina. These remains were classified as Glyptodon sp., Neosclerocalyptus cf. N. heusseri, Panochthus sp., Propraopus grandis, Megatherium cf. M. americanum, Megatherium sp., Scelidotherium cf. S. leptocephalum, Lestodon sp., Equus (Amerhippus) neogeus, Toxodon cf. T. gezi and Toxodon sp., Smilodon populator, Morenelaphus sp., Stegomastodon cf. S. platensis and Stegomastodon sp. It is possible to assign a Bonaerian-Lujanian age (middle Pleistocene-early Holocene) for this assemblage of mammals. Paleozoogeographically, the authors remark the similitude of the taxa here described and those reported for the pampean region, Santa Fe, Formosa, Paraguay and southern Bolivia. This situation permits to infer similar climatic conditions among these areas. On the other hand, a preliminary palaeofaunistic comparison with Chile shows some significative differences, specially with central Chile, while the southern and northern regions are more similar to the Argentinian Quaternary paleofauna. | en-US |
