†These are age estimates based on ages of other charcoal fragments in the same collection unit, as presented for samples 150515-6d and 150515-6e. This is true also for the two samples below, which come from collection units 171128-16 and 17128-25, for which estimates are based on dates for 171128-16a and 171128-25a, respectively.

‡Age estimate is the interval between the maximum and minimum documented ages of organics in the site.
