The goal of this paper is to analyze the lithic artefacts from layer 3 of Hornillos 2, a rockshelter located at Susques (Jujuy, Argentina), which have been dated to the beginning of the Middle Holocene (7,760-7,430 BP). These include points of the "San Martin" type, rarely mentioned in Argentine archaeology, but with a broad distribution around the Salar de Atacama and other salt-lake margins in Northern Chile, as well as the upper drainage of the Loa Rivet: Lithic analysis shows that the early Middle Holocene occupations of the site are short term, reflecting specialized activities and a technological organization related to logistical mobility. In this context, San Martin points had a long history involving multiple manufacture sequences.
