The objective of this thesis is to evaluate the temporal sensitivity of morphological variability in hafted bifaces in the Kawartha Lakes and Trent River drainage region. This provides a base of information that will enable future analyses that address the possible sources of this variability and to test the robustness of existing typological categories of hafted bifaces for relative dating. This base of information is established via the use of a principal component analysis of shape, raw material, and use-life data from a large sample of hafted bifaces in the region, using a new geometric morphometrics method designed to improve the accuracy of shape representation. The results of the analysis indicate that while certain typological categories may represent distinct morphotypes that are temporally sensitive, the majority of typological categories in the sample show high, overlapping morphological variability that cannot be confidently correlated temporally based on shape alone.
