MATERIALS AND METHODS
Two hundred and twenty crania from collections curated in Leiden, Paris, and Bamako were studied for dental diseases. In a subset of teeth (n = 175), δ13 C and δ15 N were measured in bulk dentine samples.RESULTS
δ13 C and δ15 N values vary widely (-15.4 to -6.0‰ for δ13 C, 6.0-14.8‰ for δ15 N, n = 175), and indicate diets dominated by C4 -based foods with a focus on plants; animal products played a minor role. There are significant differences between the δ13 C values from older (pre-Dogon) and younger (Dogon) periods. Frequencies of caries, antemortem tooth loss, and abscesses increase significantly through time. Individuals from northern caves have more positive δ13 C and δ15 N values than southern ones.
