Geochemical identity of pre-Dogon and Dogon populations at Bandiagara (Mali, 11th-20th cent. AD)

The application of the Bayesian mixing model FRUITS, based on bone δ13C (apatite and collagen) and bone δ15N values, suggested a dietary continuity through time, from the 11th century to today. Bone barium (Ba) content revealed very restricted mobility within the Cliff while bone δ18O values indicated that Pre-Dogon and Dogon most likely occupied the Bandiagara Plateau and the Cliff, respectively.
