Paiján obsidian points on the coastal desert of southern Peru and their source

Limited research exists on preceramic sites in south-central coastal Peru. Systematic survey and excavations at Pampa Lechuza, Ica, now confirm a Late Pleistocene-Early Holocene Paiján (13 000-9000 cal BP) occupation and identify Quispisisa-sourced obsidian Paiján points, which are the only examples currently known to use this raw material.
