Radiocarbon ages, chemical indicators including the collagen yield, %N, %C, C:N and stable isotopic values (δ13C and δ15N), and FTIR analysis of Louise de Quengo (R-EVA 3201) and Mezzena mandible (R-EVA 1395). The extracts were also analysed at the MPI-EVA in Leipzig, Germany (see section 2.6 for methods).
