Las Brusquillas 1 (partido de San Cayetano, provincia de Buenos Aires): un nuevo sitio del Holoceno tardío del área Interserrana de la región pampeana

the frequency of late holocene archaeological sites from the pampas region is higher when compared with previous periods. however, the sites corresponding to the early late holocene are scarce. in this context, the site of las brusquillas 1, located in the interserrana area and dated to ca. 3.300 years bp, becomes especially relevant for regional archaeology. the results from the technological and morphological analysis of the lithic material and the taxonomic and anatomical study of the faunal remains are presented in this paper. the objectives are to discuss the technology and subsistence of the hunter-gatherer groups that occupied the site and to contribute to the explanation of its function. the results from las brusquillas 1 show that quartzite was the preferred raw material for the manufacturing of unifacial tools, and that the main animal resource exploited was guanaco (lama guanicoe), in concurrence with archaeological evidences from other sites of similar chronology located in the interserrana area. in relation to functionality, the evidence indicates that lb1 represents a residential camp.
