Fabricación de puntas de proyectil en los niveles tardíos de la cueva Tres Arroyos 1, Tierra del Fuego

we present the results of a technological analysis focused in the bifacial reduction sequences represented in the stratigraphic levels i, ii, iii and iv of the tres arroyos 1 archaeological site, dated between 1.350 and 135 years bp. these sequences are focused in the manufacture of projectile points, known as fell iv and v which are differentially represented across the occupational sequence. even though some differences in behaviors associated to the manufacture sequences are registered, some recurrences are observed as well, such as the order of execution of operational sequences, and the tendency to choose blanks whose sizes are similar to the sizes of the finished product. the implications of observed differences are discussed.
