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 withextinct Pleistocene mammals. The following paper provides a detailed overview of materialremains found in the earliest cultural episodes at this multi-component site, dated betweenca. 12,170 14C yrs B.P. (ca. 14,064 cal yrs B.P.) and 11,180 14C yrs B.P. (ca. 13,068 cal yrsB.P.). Evidence of early occupations includes the presence of lithic tools, a concentration ofPleistocene species remains, human-induced fractured animal bones, and a selection ofskeletal parts of extinct fauna. The occurrence of hunter-gatherers in the Southern Cone atca. 14,000 cal yrs B.P. is added to the growing list of American sites that indicate a humanoccupation earlier than the Clovis dispersal episode, but posteriorto the onset of the deglaciationof the Last Glacial Maximum (LGM) in the NorthAmerica.
