- Addressing human mobility in Iberian Neolithic and Chalcolithic ditched enclosures: The case of Perdigões (South Portugal)Publication . Valera, António Carlos; Žalaitė, I.; Maurer, Anne France; Grimes, V.; Silva, Ana Maria; Ribeiro, S.; Santos, J. F.; Dias, Cristina BarrocasTo access the role of mobility in the social trajectory of Late Neolithic and Chalcolithic societies in the South of Portugal (Southwest Iberia) a project was design to address the human, animal and object/raw material flow present at Perdigões enclosure. Perdigões, located in the inner Alentejo region, has a long chronology from Late Middle Neolithic to Late Chalcolithic/Early Bronze Age (middle 4th and 3rd millennium BC). It is a large complex of ditched enclosures (with at least 16 ditches), presenting several funerary contexts, an abundance of faunal remains and significant concentrations of exogenous materials in tombs. In this study human and animal mobility are addressed through 87Sr/86Sr isotopic analysis. 69 individuals dating from Late Neolithic and Chalcolithic, with provenance from 9 different archaeological contexts inside the enclosures (tombs, ditches and pits) were analysed. Human data are presented along with previously published strontium isotope ratios from fauna (n = 28; Canis familiaris, Bos taurus, Sus sp., Ovis/Capra, Cervus elaphus, Equus sp.) from the same chronological range and several contextual provenances (Zalaite et al., 2018). Plant samples (n = 20) that cover local and peripheral lithologies were used for establishing local bioavailable strontium isotope ranges. To compare with the Perdigões results, 9 human samples from 3 megalithic monuments (Cebolinhos 1, Comenda 1 and Vidigueiras 2) of the local settlement network were also analysed. The results show a significant scaled mobility of humans and animals in Perdigões, a contextual variation between the funerary contexts within the site and a significant contrast with the individuals from local megalithic monuments. These results, combined with other archaeological data at the site, agree with the interpretation of the site as a large aggregation centre integrated in large scale interaction networks.

- Diet and mobility of fauna from Late Neolithic–Chalcolithic site of Perdigões, PortugalPublication . Žalaitė, I.; Maurer, Anne-France; Grimes, V.; Silva, Ana Maria; Ribeiro, S.; Santos, J.F.; Barrocas Dias, Cristina; Valera, António CarlosPerdigões is located in the Alentejo region of south-eastern Portugal, with occupational phases dating from the Late Middle Neolithic to Late Chalcolithic/Early Bronze Age (middle 4th and 3rd millennium BCE) periods. It is a complex site that can be considered as a centre of social aggregation and a part of a larger settlement network. In this study, the nature of animal subsistence patterns as well as husbandry management practices and mobility are examined using stable carbon and nitrogen isotopic values from bone collagen of 35 archaeological faunal samples (Canis familiaris, Bos taurus, Bos primigenius, Sus sp., Ovis/Capra, Cervus elaphus, O. cuniculus, Equus sp.) and strontium isotope (87Sr/86Sr) analysis of 23 enamel samples. To provide necessary biological 87Sr/86Sr baseline data, the strontium isotopic composition of 14 modern plant samples were measured. The stable carbon and nitrogen isotope data shows that animals subsisted on a selection of C3 terrestrial resources, with subtle differences in animal husbandry practices in domesticated animals, while strontium isotope analysis shows that<5% of analysed fauna is consistent with the local bioavailable strontium isotopic range. Other animals can be divided into two clusters – those having strontium isotope values either lower or higher than the bioavailable range, showing that most of the fauna browsed and grazed within 10 km of the site's surrounding landscape, which is not such an unusual practice during prehistoric times.
