Extended data Figure 9 -

Location of the laser ablation spot (150 microns) along the enamel and dentine for StS 51A (A) and StS 28C (B). Circles with red filling correspond to the first point (1) and yellow filling to the last point (9 for enamel and 6 for dentine). The table below shows the 87Sr/86Sr isotopic ratio and associated errors for each laser ablation spot measured above. All values measured in both teeth (including Dentine 6 of StS 28 with associated error) correspond to the Malmani dolomite values surrounding Sterkfontein (87Sr/86Sr 0.723 < Malmani dolomite < 0.734)3, showing limited mobility for both specimens.
