  1. The sample KLR-11251a/C94 is cortical bone tissue from St James. KLR-12290/C93 is an extract of the organic phase from the encrustation coating found in the canal. The δ13C is the stable isotope ratio measured by IRMS. The 14C dates are calibrated into calendar ages using the IntCal20 curve [50]
