ABSTRACT

The Arroyo Seco 2 site contains a rich archaeological record, exceptional for South America, to explain the expansion of Homo sapiens into the Americas and their interaction with extinct Pleistocene mammals. The following paper provides a detailed overview of material remains found in the earliest cultural episodes at this multi-component site, dated between ca. 12,170 14C yrs B.P. (ca. 14,064 cal yrs B.P.) and 11,180 14C yrs B.P. (ca. 13,068 cal yrs B.P.). Evidence of early occupations includes the presence of lithic tools, a concentration of Pleistocene species remains, human-induced fractured animal bones, and a selection of skeletal parts of extinct fauna. The occurrence of hunter-gatherers in the Southern Cone at ca. 14,000 cal yrs B.P. is added to the growing list of American sites that indicate a human occupation earlier than the Clovis dispersal episode, but posterior to the onset of the deglaciation of the Last Glacial Maximum (LGM) in the North America.

ABSTRACT

La funcionalidad de la laguna de Lobos declina paulatinamente, debido no solo a sus caracteristicas fisicas y a la de su dinamica acuatica,sino tambien su calidad ambiental se encuentra comprometida, por el incremento de las actividades humanas y su impacto en el todo el area de la cuenca, lo que inevitablemente acelera el proceso de envejecimiento prematuro
