, Material Received: Laboratory Number Sample Code Number Conventional Radiocarbon Age (BP) or Percent Modern Carbon (pMC) & Stable Isotopes Calendar Calibrated Results: 95.4 % Probability High Probability Density Range Method

, Submitter Material: Charcoal (charred material) acid/alkali/acid Pretreatment: Charred material Analyzed Material: Analysis Service: AMS-Standard delivery Percent Modern Carbon: -173.43 +/-3.09 o/oo

, All work was done at Beta in 4 in-house NEC accelerator mass spectrometers and 4 Thermo IRMSs. The "Conventional Radiocarbon Age" was calculated using the Libby half -life (5568 years), is corrected for total isotopic fraction and was used for calendar calibration where applicable. The Age is rounded to the nearest 10 years and is reported as radiocarbon years before present (BP), "present" = AD 1950. Results greater than the modern reference are reported as percent modern carbon (pMC). The modern reference standard was 95% the 14C signature of NIST SRM-4990C (oxalic acid). Quoted errors are 1 sigma counting statistics. Calculated sigmas less than 30 BP on the Conventional Radiocarbon Age are conservatively rounded up to 30, Results are ISO/IEC-17025:2005 accredited. No sub-contracting or student labor was used in the analyses, p.13
