The high molecular weight organic fraction of bone or tooth from 139 individuals from twelve archaeological sites in Virginia and three sites in North Carolina was isolated via a dialysis procedure and analyzed for stable nitrogen and carbon isotopic composition. The sites represent three physiographic provinces: the Coastal Plain, the Piedmont, and the Appalachian Valley. Three time periods were examined: the Middle Woodland (0 - A.D. 900), the first part of the Late Woodland (A.D. 900 - 1400), and the second part of the Late Woodland (1400 - 1600). The δ13C values for six of the sites reflect a strong C3 plant component of the diet; the remaining sites had a strong C4 plant component. A shift from predominantly C3 plants in the Middle Woodland period to predominantly C4 plants at the start of the Late Woodland was observed. The δ15N values suggest a diet rich in terrestrial animal proteins for all three time periods. Piedmont sites had the most diverse diet; Appalachian Valley sites had the least diverse. Coastal Plain sites reflected a substantial marine or aquatic influence in the diet. The temporal patterns observed for δ13C values are consistent with the general trends seen throughout the eastern part of North America. Note: Abstract extracted from PDF file via OCR.
