Archaeology, chronology, and age‐diet insights of two late fourth millennium cal BC pit graves from central southern Iberia (Córdoba, Spain)

Abstract

AbstractThis study presents the isotopic ratios, radiocarbon datings, and anthropological analyses of five (N = 5) Early Copper Age individuals from two archaeological sites (Arruzafa and Iglesia Antigua de Alcolea) of the Middle Guadalquivir Valley near the city of Córdoba (Spain). Four had been buried in the same grave, possibly in a single event or in a very short time lapse. The collagen residue analyses of the individuals offer δ13C values ranging between −20.08 and −18.4 and δ15N values between 8.57 and 11.15. The findings indicate that the infant and the elderly had, respectively, the richest and poorest animal protein diets, the first likely as a result of nursing. The combined study of these five individuals offers an interesting approach to a small segment of population of the farming communities occupying this territory at the beginning of the Copper Age (3200–3000 cal BC).
