RT info:eu-repo/semantics/article T1 Dietary inferences from dental microwear patterns in Chalcolithic populations from the Iberian Peninsula: the case of El Portalón de Cueva Mayor (Sierra de Atapuerca, Burgos, Spain) and El Alto de la Huesera (Álava, Spain) A1 García González, Rebeca A1 Sánchez Puente, Zuriñe A1 Arsuaga, Juan Luis A1 Carretero Díaz, José Miguel K1 Chalcolithic diet K1 Northern Plateau K1 Age-related dietary habits K1 Anatomía humana K1 Human anatomy K1 Restos humanos (Arqueología) K1 Human remains (Archaeology) K1 Alimentación K1 Diet AB Dietary habits are inferred through dental microwear analysis in humans from two Chalcolithic sites located on the Iberian Northern Plateau: El Portalón de Cueva Mayor and El Alto de la Huesera. The pattern of dental microwear was established on the buccal surfaces of permanent and deciduous molars, on the bottom of facet 9 on the occlusal surface of lower molars and on the incisal surfaces of deciduous incisors. Our findings suggest that during the Chalcolithic, the diet of populations from the Northern Plateau is less abrasive than that at the Mediterranean coast, due mainly to high meat consumption. The differences in diet are related to environmental factors, which are more appropriate for animal husbandry on the Northern Plateau. The consumption of meat is not equivalent in sub-adult and adult individuals from our samples located on the Northern Plateau. Younger individuals show a harder diet with less meat intake than older ones.
