New 3D morpho-technological data on fishtail points from tropical lowlands, Piauí State, Northeastern Brazil
(Taylor and Francis Ltd., 2024-01-01)
Here we report two newly discovered Fishtail projectile points from Jurema and Anísio de Abreu, southern Piauí, northeastern Brazil. These are two complete bifacial pieces made of flint and chalcedony. Only one Fishtail point has been previously reported north of the 22° parallel. This paper significantly adds new data by providing a detailed analysis of the morphology, technology, use-wear, and a 3D semi-automated analysis of this important cultural marker in South America.

Quartz Crystal Fishtail Projectile Point and Paiján Technology from the Pampa Lechuza Site, South-Central Coastal Desert of Peru
(Taylor & Francis, 2025-01-01)
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.
