Materias primas líticas y cronologías de puntas pedunculadas tipo Fell V entre las cuencas de los ríos Chico -curso inferior y medio- y Santa Cruz (Provincia de Santa Cruz)

the aim of this study is to evaluate the raw material variability of archaeological projectile points similar to the ones recovered by bird (1993) in the period v of his cultural sequence. the analyzed area is located between chico and santa cruz rivers (province of santa cruz). in turn, the present work attempts to determine the timing of those projectile points from archaeological researches and historical documentation. as a consequence of this endeavour, the points are located between ca.1000 and 1700 ac, which is prior to the introduction of horses in patagonia. finally, the raw material analysis of these points allowed us to state that east groups had more direct access to the non-local raw materials -such as black obsidian- than people located further west, in the north of lago argentino.
