VIGNA, Mariana; GONZALEZ, María Isabel  y  WEITZEL, Celeste. Los cabezales líticos de la microrregión del río Salado bonaerense, Argentina: Diseños e historias de vida. Intersecciones antropol. [online]. 2014, vol.15, n.1, pp.55-69. ISSN 1850-373X.

This paper analyzes fifteen lithic projectile points, both complete and fractured, recovered from different excavations, surveys and surface collection carried out in five archaeological sites in the micro-region of the Salado river. These occupations are dated back to the late Holocene period. The study of the biography of these artifacts led us to infer different aspects related to rock selection, manufacturing sequences, types of fracture, use, maintenance, discard, and postdepositional processes. In this way, we were able to differentiate two types of weapons among the basic, maintained and transformed designs: lithic arrow points and hand-held weapon points. They could have been used to obtain a variety of animal resources found in situ employing different types of hunting strategies. Finally, we include aspects of the extended life history of these artifacts as they relate to their contemporary use.

Palabras clave : Lithic points; Objects biography; Salado river region; Late Holocene.
