CHARLIN, Judith; BORRERO, Luis A.  and  GOMEZ OTERO, Julieta. First human occupations in Potrok Aike 1 rockshelter (Santa Cruz): stone tools, bones and paleoenvironmental data. Rev. Mus. Antropol. [online]. 2018, vol.11, n.2, pp.23-38. ISSN 1852-060X.

Unpublished information from the lower levels of Potrok Aike 1 Rockshelter, Santa Cruz, Pali Aike Volcanic Field is presented. Lithic and archaeofaunal materials were recovered between 97 and 152 cm at Square C of the rockshelter. This evidence is related with available paleoenvironmental information from deep cores obtained in the Potrok Aike lagoon. Results indicate changes and continuities in the use of faunal remains and lithic raw materials between the older (≥2300≥1300 years BP) and recent (<1300 years BP) occupations. Also changes in the intensity of use of the site concordant with climatic variation were identified. Finally, by comparison with previous archaeological results, the significance of the human occupations recovered at the Potrok Aike Rockshelter is evaluated at the scale of the site, the locality and the region.

Keywords : Potrok Aike 1 Rockshelter; Pali Aike Volcanic Field; Stone tools; Bones; Paleoenvironment.
