Dietary inferences through dental microwear and isotope analyses of the Lower Magdalenian individual from El Mirón Cave (Cantabria, Spain)

•We infer diet in the Red Lady through dental microwear and isotopic analysis.•Results from both independent approaches are consistent.•Lower Magdalenian individual form El Mirón Cave consumed a mixed diet, implying a generalized exploitation of the environment.

Dietary habits are inferred from dental microwear and isotope analyses of the Magdalenian human individual from the site of El Mirón, dated to 15,460 ± 40 BP. The pattern of dental microwear was established on the buccal surface of the lower fourth premolar and on the bottom of facet 9 on the occlusal surface of the lower third molar. The results obtained through analysis of different surfaces are consistent and indicate a mixed diet for this Lower Magdalenian individual, including meat, aquatic resources and vegetables. These results are in agreement with those obtained through isotope analysis. This implies a generalized exploitation of the environment as has been previously established in other Late Upper Palaeolithic specimens.
