An experimental approach to the study of interpersonal violence in Northeastern Patagonia (Argentina), during the late Holocene

► We incorporate an experimental approach to study violence patterns in NE Patagonia. ► We analyzed a sample of human skulls (n = 986) in order to detect metal tools marks. ► We used swine skulls as proxies for human skulls and original swords. ► No differences were found between archaeological and experimental marks. ► No significant increases were registered until the Hispanic-indigenous contact.
