Resumen

Multi-isotope analyses at an individual level can offer valuable information on identity. Here, we reconstruct the dietary life-history of a Late Mesolithic (ca. 5500 cal. BC) woman buried in Aizpea rockshelter (northern Iberia). To this end, we combine δ13C and δ15N isotope analyses of bone collagen and tooth dentine. We also analyse a wide range of coeval faunal and plant remains to ascertain the variability of baseline isotopic signature. Results suggest a broad-spectrum diet with significant changes, including two marked dips at 8.5 and 11.5 years old, and a progressive decreasein δ13C and δ15N from adolescence onwards. The dips may relate to sustained physiological stress or famine, as they coincide with formation ages estimated for various linear enamel hypoplasias identified, while the sustained drop in isotope values may be due to a progressively greater contribution of plants to diet, which could be linked with a change in social status.
