Macro sample 95


This sample comes from initial salvage excavations in the East Locus at Los Pozos. The reliability of this date has been questioned by Gregory (2001), and Mabry (2005:115) points out that there was no 13C/12C measure provided. Because the sample size was so small, extended counting was required. For these reasons, and because it is seven centuries earlier than the earliest of a suite of more than 50 subsequent AMS maize dates obtained from all loci at the site, we exclude it from calibration analysis (See also Merrill et al. 2009).
