Even the calibrated 95% confidence interval on a radiocarbondate may not encompass the true age of the dated material. On the one hand, the calibrated 2-sigma radiocarbondate of a. d. 690-890 is relatively early. A single radiocarbondate has also been obtained (note 41 below). This study is anchored by only a single radiocarbondate that must bear an enormous interpretative weight. In 1964 a radiocarbondate put the statue's age at 350 years old.

The project obtained two radiocarbon dates from this feature. With this site context for background, the radiocarbon dates will be discussed with details of their precise archaeological contexts. The calendar-year dates are based on calibrated radiocarbon dates that have errors of + 50-100 years. Organic remains within the cores allow radiocarbon dates to be obtained for the sediments and hence for pollen recovered at different depths within the cores. The third piece of evidence lies in the presence of cremated bones found inside the funerary ollas, and the fourth is the radiocarbon dates. We obtained two corrected radiocarbon dates from the interior fill of the shaft. It would have been useful, however, to have a table summarizing all the radiocarbon dates in one place. For each site, they document the excavated features in detail, describe the unexcavated portions, and discuss the intra-site chronology, supported with radiocarbon dates where these are available. Radiocarbon dates can verify or correct previously proposed correlations between ceramic assemblages and calendrical inscriptions and tighten our chronologies.
