Fig. 3: Box and whisker plots showing the range and distribution of intra-tooth 87Sr/86Sr, δ18O, and δ13C data for individual horses, reindeer and mammoth from Königsaue Layer A and Breitenbach.

a combined intra-tooth 87Sr/86Sr values, b intra-tooth δ18O values, and c combined intra-tooth δ13C values for Equus sp. (n = 2), R. tarandus (n = 3), and M. primigenius (n = 1) individuals from KÖA. d combined intra-tooth 87Sr/86Sr values, e combined intra-tooth δ18O values, and f combined intra-tooth δ13C values for Equus sp. (n = 3) and R. tarandus (n = 7) individuals from BRE. Each box represents one individual. Light pink boxes represent equid M2-M3 teeth in the mandible, light purple boxes represent the isolated M1 equid tooth, dark purple boxes represent isolated M3 equid teeth. Dark teal boxes denote isolated reindeer teeth (all M3) and light teal boxes represent reindeer M2-M3 teeth in the mandible. The blue box represents the single isolated mammoth tooth (M4).
