This maize sample (ECA-2) comes from the Central Plaza area and was recovered in construction fill between floors 1 and 2. As with T0-10586, this sample date is too old for its context and may have be contaminated by some post-depositional process: "Although there was no external sign of it, it is likely that contamination occurred" (Chapdelaine et al. 2009:194). Since it was recovered in construction fill, the cob could also have been brought to the site in a load of fill that originated as part of an earlier, as yet undetected deposit some distance away.
