Staff of the William & Mary Center for Archaeological Research (WMCAR), working closely with the APVA's Jamestown Rediscovery project, examined a sample of 179 hafted bifaces recovered from excavations in and around the site of the original Jamestown fort. Excavation contexts ranged from plowzone to secure feature deposits. The purpose of the analysis was principally to evaluate the function and origin of the many small triangular projectile points in the sample, but also to determine the broader temporal range of occupation in the fort area. An inventory of the examined hafted bifaces is provided in Appendix A.

WMCAR staff recorded a standard set of attributes for each artifact. These included qualitative attributes such as context, raw material, and breakage, as well as metric attributes for maximum length, maximum width, and weight. Most metric attributes were recorded only for unbroken artifacts.
