Micro sample 464

Information

Ten maize starch grains (plus 5 tentatively identified as such) were recovered from a handstone, or trianguar-shaped grinding stone (Artifact No. CL-82b) in Unit 1 Level 11 (Dickau et al. 2007: Table 1; Dickau 2010). The radiocarbon date most closely associated with this artifact is TEM-123, obtained from a charcoal sample (Ranere and Cooke 1996:52).
