AMS RADIOCARBON DATING AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM THE PIGG SITE (5MT4802), COLORADO

Five charred Zea mays (corn) cob fragments and one charred Phaseolus vulgaris (bean) fragment recovered from two room blocks and a kiva at the Pigg Site (5MT4802) in Montezuma County, Colorado, were submitted for identification verification and AMS radiocarbon dating. Also submitted for organic residue analysis were several painted ceramic mug fragments that were used to line a sipapu in the same kiva from which the corn and bean samples were recovered. Organic residue analysis on select sherds will be used to determine if the fragments belonged to the same mug, the possible use of the mug prior to lining the sipapu, and what might have been contained in the mug. The ceramic fragments were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR).
