Animal consumption and social change: the vertebrates from Ditch 7 in the context of a diachronic approach to the faunal remains at Perdigões enclosure (3400-2000 BC)

The results from the study of the faunal assemblage from ditch 7 of the Perdigoes enclosure (Reguengos de Monsaraz, Portugal) are presented. Dated to the Chalcolithic and the transition to the early Bronze Age it comprises a total of 3380 remains. Results show the rele- vance of swine, caprines, cervids, bovines and equids and their diachronic oscillation. Indicators of butchering and consumption were recorded, comprising cutmarks, anthropogenic breakage, thermo-alterations and tooth marks, the latter mainly of a carnivore origin. The spectra obtained were compared within the scope of the Perdigoes chronology, from the late Middle Neolithic to the transition to the early Bronze Age (3400-2000 BC), thus representing a first approach to the diachronic behaviour of vertebrate consumption at the site. Domesticated species are prevalent but changes in the domesticated/wild ratio are evident with a wild input, mainly from red deer, of significance in the late Middle Neolithic and in the transition to the early Bronze Age, whereas the Late Neolithic and Chalcolithic periods have a growth in the domesticated component.
