Fishtail projectile points, found from Central America to southern South America during the Late Pleistocene, are typically flint-based but occasionally crafted from quartz. This work examines quartz crystal specimens from Peru’s Pampa Lechuza site (Ica Valley), dated to the Late Pleistocene–Early Holocene, including Fishtail and Paiján Points. The co-occurrence of these technologies in south-central Peru suggests a more intricate scenario of Andean peopling during the Pleistocene–Holocene transition.
