Mind the Gap: Maize Phytoliths, Macroremains, and Processing Strategies in Southern New England 2500–500 BP

Abstract

Mind the Gap: Maize Phytoliths, Macroremains, and Processing Strategies in Southern New England 2500–500 BP. This study presents preliminary results from a phytolith analysis of carbonized food residues and sediment soils from sites in southern New England (Connecticut and Rhode Island) dating 2500–500 BP. Phytolith analyses of carbonized food residues from sites across northeastern North America outside of southern New England demonstrate that maize (Zea mays L.) was introduced to the region as early as 2300 BP, hundreds of years before major shifts in settlement strategies became widespread. Phytolith evidence for maize in eastern North America likewise appears hundreds of years earlier than most maize macroremains, such as kernels, cobs, and cupules, appear. This has puzzled researchers attempting to piece together how maize was first circulated and used in the Eastern Woodlands. Preliminary phytolith analysis of carbonized food residues from seven sites indicates that, consistent with research outside the study area, at least some groups in southern New England cooked maize as early as 2300 BP. The results also indicate that maize cooking practices varied in ways that likely reflect broader subsistence strategies and that may explain the temporal gap between maize phytoliths and maize macroremains.
