Morphological variability in Clovis style hafted bifaces across North America.

摘要

This study examines morphological variability of Clovis style hafted bifaces from across North America. In total 695 Clovis hafted bifaces were analyzed. These data are analyzed using a Lithic Technological Organization perspective. The effects of raw material availability, site type, retouch and resharpening are considered. Several interesting trends in the morphological variability of Clovis hafted bifaces are revealed. Each of these factors are revealed to have significant effects on the morphology of Clovis hafted bifaces. These effects can bias future studies of Clovis hafted biface morphology. In addition, the Northeast culture area is found to be significantly different from the rest of the Clovis hafted biface sample. This study advances the knowledge of Clovis hafted biface technology and surveys the variability in this artifact type across geographic space and present a firm foundation on which further studies of Clovis hafted bifaces may stand.
