First insight into the Neolithic subsistence economy in the north-east Iberian Peninsula: paleodietary reconstruction through stable isotopes.

OBJECTIVES The study of subsistence strategies among Neolithic communities in north-east Iberia, late-fifth to early-fourth millennia cal BC, enables a more in-depth study of the activities and behavior of the inhabitants of this region, where paleodiets have been little studied. The objectives of this study are, therefore, to determine the diet and subsistence patterns of those communities and to consider whether any relation existed between their subsistence strategies and environmental, geographic, and/or social factors. MATERIALS AND METHODS Bone samples from 25 middle Neolithic human individuals at seven archeological sites and comparative faunal samples were analyzed, and compared with contemporary series in Mediterranean Europe. Carbon and nitrogen isotope ratios (δ13 C and δ15 N) of bone collagen were studied to determine the dietary patterns. RESULTS Dietary habits proved to be similar between communities, apart from some interpopulational variations in subsistence strategies. Their diet was based on C3 terrestrial resources with a major vegetal protein component. DISCUSSION The reported variations in interpopulational subsistence strategies among the compared Mediterranean societies do not seem to be directly related to the settlement region. Together with archeological data, this indicates the influence of socioeconomic factors in the Neolithic human diet. A general tendency toward a lesser use of aquatic resources is seen in this period in Iberia and the rest of the Mediterranean, as also documented for contemporary communities in the west and north of Europe. The data obtained will be important for further studies of socioeconomic patterns in European Neolithic societies.

Human diet and the chronology of neolithic societies in the north-east of the Iberian Peninsula: the necropolises of Puig d’en Roca and Can Gelats (Girona, Spain)

Radiocarbon and palaeodiet information has been obtained for two Neolithic necropolises in the north-east of the Iberian Peninsula: Puig d’en Roca and Can Gelats (Girona, Spain). Although Puig d’en Roca is one of the most important necropolises in this period, it is also one of the least known as, following its excavation in the 1950s and 1960s, it has scarcely been restudied archaeologically. Can Gelats is one of the latest funerary sites of this period to be excavated and therefore is little known to the scientific community. Two key issues in the study of Neolithic communities in the western Mediterranean are addressed here. Few radiocarbon determinations have been obtained at funerary sites and they have usually been applied to a very small number of individuals in each cemetery (one or two dates). In a similar way, palaeodiet analysis of Neolithic cemeteries has rarely been attempted, and therefore the information presented here is of great importance to understand the diet in those societies. This paper presents a new series of dates for two of the most important Neolithic necropolises in north-east Iberia and approaches the subsistence patterns of the populations buried there.
