All charcoal samples were sent to Waikato, NZ, where they were pre-treated by washing in hot HCl, rinsed and treated with multiple hot NaOH washes. The NaOH insoluble fraction was treated with hot HCl, filtered, rinsed and dried. Despite their relative proximity squares B8 and B10 show internal variation.
* 13C measured by AMS. Result not reported
#13C measured by CRDS [38].
NB the EDM data point for sample B10-XU17-1 was erroneous, so the exact provenance of this age determination is not known.
