From: Surgical amputation of a limb 31,000 years ago in Borneo
a, Tooth section and polished Uranium-series analyses (red rectangles indicate location of laser rasters), with Trace elemental map: distribution of uranium in the M3 dental tissues. b, Dose response curve (DRC) obtained using McDoseE 2.0 program60 with an iteration of 100,000. c, Dose equivalent De frequency distribution; d, Age distribution frequency for the third molar (M3). e, Table summarising parameters and data used for modelling the ESR age (2-sigma). f, Results of the Bayesian model age sequence.
