Abstract

Megalithism has been repetitively tied to specialised herding economies in Iberia, particularly in the mountainous areas of the Basque Country. Legaire Sur, in the uplands of Álava region, is a recently excavated passage tomb (megalithic monument) that held a minimum number of 25 individuals. This study analysed the carbon, nitrogen, oxygen, and strontium isotope ratios of 18 individuals, in a multi-tissue sampling study (successional tooth enamel sampling, incremental dentine sampling, and bulk bone collagen sampling). The results provide a high-resolution reconstruction of individual mobility, weaning, and dietary lifeways of those inhumed at the site. Oxygen and strontium isotope analysis suggest all individuals come from a similar, likely local, geological region, aside from one biological female who presents a notably different geographical birthplace, weaning, and dietary life history than the rest of the burial population. Comparisons to other nearby megalithic sites (∼35km as the crow flies), located in a valley area, reveal that, whilst sharing the same mortuary practices, these individuals held notably different lifeways. They highlight notably earlier ages of cessation of nursing (≤2 years at Legaire Sur vs. ≥4 years in other megalithic tombs), and a greater dependence on pastoralism than previously observed in lowland megalithic graves. The results from Legaire Sur reveal the complexity of the Late Neolithic-Chalcolithic transition in north-central Iberia, categorising yet another separate socio-economic group with distinctive lifeways inhabiting the region.

Abstract

During the early medieval period (5th–9th century CE), the North Sea coastal societies were involved in long distance maritime trade relations, which resulted in a pronounced mobility of individuals throughout the North Sea area. This work presents the first isotope data from human remains on diet and mobility from early medieval Belgian coastal populations. A total of 23 out of 51 excavated individuals from the archaeological site of Koksijde, Belgium (7th–8th century AD), was selected for isotope and elemental analyses (δ13Ccol, δ15N, δ18OP, δ13Cap, δ18OC, 87Sr/86Sr and [Sr]). The high δ15N values of part of the individuals buried at Koksijde indicate that high trophic level ranked fish was included in their diets, suggesting an intensive exploitation of marine food sources. The δ18O values are not compatible with the predicted ‘local’ values while the strontium isotope ratios have values close to that of seawater (0.7092). Either the actual oxygen isotope values in early medieval Belgium are offset by 1 or2‰ compared to the current meteoric water predictions, or the population came from somewhere else. Whether or not this was linked to the population's mobility is difficult to assess based on their δ18O and 87Sr/86Sr values. Nonetheless, the study of the population at Koksijde provides new insights into the lives of the early medieval coastal Belgian societies.
