“…The tusks from the gomphothere skull are missing (Figure ), and there are no geological processes to explain their absence. As a reference, even in the Trebal‐1 site in central Chile, which is associated with a high‐energy fluvial environment, both tusks were recovered attached to the gomphothere skull (Labarca, Alberdi, Prado, Mansilla, & Mourgues, ). Notably, in the Monte Verde site, a piece of ivory gomphothere tusk was transported to the camp and an artifact was even produced from it (Dillehay, ).…”

In this study we used a multidisciplinary approach, coupling morphological, geological, geochemical, and statistical analyses to investigate the provenance of rhyodacitic and dacitic glass knapped at the Pilauco site (40°34′11” S, 73°06′17” W; 13,570 ± 70–12,540 ± 90 14C year BP) in northwestern Chilean Patagonia. A morphotechnological analysis was performed on the entire lithic assemblage, which is composed of cores, retouched and unretouched unifacial flakes, and small pieces of debitage, some of them closely associated with Notiomastodon aff. N. platensis gomphothere bones. Sixty‐two archeological and geological samples were analyzed by inductively coupled plasma mass spectrometry revealing a wide range of basaltic to rhyodacitic compositions. The archeological knappable dacitic and rhyodacitic glasses were recovered from pebbles deposited mainly on a beach away from the site, as deduced by the presence of minute and dense crescentic percussion marks on the cortexes. Geochemical trace element analysis suggests that the Puyehue–Cordón Caulle Volcanic Complex is the most likely source for the volcanic glass artifacts at Pilauco. The new morphotechnological and provenance record and improved stratigraphic sequences highlight the Pilauco site as an important contribution for the diversity of the South American geoarchaeological context.
