Abstract
- Abstract: Paso Otero archaeological locality (Pampean region, Argentina) has provided detailed paleoenvironmental reconstructions and faunal assemblages from the Pleistocene/Holocene transition and Early Holocene. This time span is represented by Paso Otero 5 (c. 10 450–10 200 14C BP; 12 593–11 353 cal. BP) and Paso Otero 4 (c. 9900–7700 14C BP; 10 667–7982 cal. BP). Palaeoenvironmental studies have been carried out on the basis of data derived from geoarchaeological, sedimentary, palynofacies, pollen, diatoms and silica microremains. Unlike other areas of the Pampean region, bone assemblages from Paso Otero include high representation and diversity of taxa. In this paper, paleoenvironmental reconstructions and faunal assemblages from both sites are integrated in order to discuss the consistency of the inferences derived from the two lines of evidence, its contribution to the paleoecological scenarios, and to faunal extinctions. It is suggested that not only hunting pressure but the mere presence of humans was a factor in ecosystem disturbance and is the most parsimonious explanation for the process of extinction.
