DENTAL ATTRITION AT THE INDIAN KNOLL (15OH2) AND BLACK EARTH (11SA87) SITES: EXTREME WEAR AS A STRESSOR IN LATE ARCHAIC POPULATIONS OF THE OHIO VALLEY

Abstract

This study investigates comparatively the prospect that excessive dental wear in certain Late Archaic populations in eastern North America was caused by extensive shellfish consumption and the associated ingestion of grit. Specifically, the amount and rate of dental wear at Indian Knoll, a large shell midden site in western Kentucky, are compared to those at the Black Earth site, a contemporary occupation in southern Illinois with no evidence of shellfish utilization. Results show no significant differences in dental wear between Indian Knoll and Black Earth and point correspondingly toward the alternative prospect that the intensification of Late Archaic food-processing technology using stone-grinding and hot-rock cooking was the proximate cause. Such technologies provided short-term caloric benefits, but long-term disease consequences for adults of child-bearing age. A decrease in young adult dental wear correlates with the adoption of both food production and pottery in the subsequent Woodland period.
