Do early Paleoindian point blades carry culturally significant shape information? Modules versus complete points using geometric morphometrics

•Comparing the effectiveness of modules to complete Clovis points in Geometric Morphometrics shape analysis.•Variation imposed by resharpened Clovis point-blades is a product of patterned cultural behavior.•Clovis fluted-point resharpening trajectories were culturally transmitted alongside manufacturing protocols.•Analysis of the complete point provides the most parsimonious representation of Clovis-point shape if the goal is to identify regional differences.
