Analysis of bone arrowheads from prehistoric Argentina has unveiled evidence of sophisticated craft production among communities that thrived over 700 years ago. The study demonstrates that Late Prehispanic peoples in the Sierras de Córdoba developed standardized manufacturing techniques passed down through family lines, shedding light on how these mobile societies organized their daily lives and technological traditions. Dr. Matías Medina and his colleagues from Argentina's National Scientific and Technical Research Council examined 117 bone artifacts dating from approximately 1220 to 330 years before present. Their research addresses a significant gap in understanding South American prehistoric technology, revealing that these communities practiced flexible mixed economies combining hunting, gathering, and farming while maintaining high mobility through seasonal camps.
