This thesis examines morphometric variability and decorative variability and complexityat the intervessel and intravessel levels in samples of complete and near-complete Middle and Late Woodland vessels. The purpose of this study is to determine how a better understanding of variability in Middle and LateWoodland period pottery can help interpret fragmentary assemblages and supplement minimum number of vessels estimates (MNV) and estimated vessel equivalents (EVE): two common methods of pottery quantification. This study also permitted the full characterization of the Charleston Lake and South Lake vessels with associated photographs. The results of this study indicate that sherd thickness and design can be used to confidently assign vessel fragments to single vessels, thereby improving minimum number of vessels estimates, and the process of measuring brokenness and completeness for estimated vessel equivalents. Three sherd thickness conversion indexes provide archaeologists with a way to relate non-diagnostic and non-fitting sherds to their original vessels by the measure of sherds in relation to rims or paired portions (eg. Rim and neck, neck and shoulder, body and shoulder, and body and base). With the use of the sherd thickness conversion indexes, an efficient method of MNV estimation is proposed.
