Using Artifact Shapes to Reconstruct Social Interaction during the Late Paleoindian and Early Archaic Periods in the Southeast

In this chapter, Thulman studies the notching and hafting artifact morphology change in the Southeast coast, the Gulf and Atlantic coasts, and the Ohio Valley. Chronology is key to formal studies, so he examines radiocarbon dates using Bayesian methods to isolate the rate of change in designs. Typology is likewise examined as a key to isolating variation at a regional level. Better typologies are sought using landmark-based geometric morphometrics (LGM). Thulman singles out the abruptness of notching as related to the robust social networking among EA groups. Florida, as part of the “Dalton Phenomenon,” is a curious outlier.
