Molecular evidence of changing foodways across the Mississippian transition at the George Reeves site (11S650)

ABSTRACT

The George Reeves site (11S650) is a multicomponent village on the bluffs in the central American Bottom, Illinois. The site was occupied from the Late Woodland Rosewood phase through the Mississippian Lohmann phase. Pottery use and dietary variation between the Late Woodland and Emergent Mississippian occupations at the site were explored through stylistic analysis, pottery residue analysis, and compound-specific carbon isotopic analysis of pottery residues. Although more samples should be analyzed, diet and pottery use at George Reeves seems to have been varied, with maize present by cal AD 900–1000, but comprising a relatively small portion of lipid residues in pottery. Residue analysis indicates a C₄ presence in 5 of 16 sampled pots from the early Emergent Mississippian deriving from either maize or from meat from animals consuming maize. Pottery residues were mixed, showing C₃ and C₄ plants as well as meat and fish or shellfish. One residue showed a high incidence of C₄ contribution, most likely from Portulaca oleracea (common purslane), as well as large amounts of fish or shellfish and another C₃ plant. Residue from a ceramic pipestem indicates that maize may have been smoked, probably in the form of maize silk mixed with other nontobacco plants.
