Clovis culture
Material culture

A feature considered to be distinctive of the Clovis tradition is overshot flaking, which is defined as flakes that "during the manufacture of a biface are struck from prepared edges of a piece and travel from one edge across the face", with limited removal of the opposite edge. Whether or not the overshot flaking was intentional on the part of the stoneknapper has been contested, with other authors suggesting that overface flaking (where flakes that travel past the midline but terminate before reaching the opposite end are removed) was the primary goal. Other elements considered distinctive of the Clovis culture tool complex include "raw material selectivity; distinctive patterns of flake and blade platform preparation, thinning and flaking; characteristic biface size and morphology, including the presence of end-thinning; and the size, curvature and reduction strategies of blades". It has long been recognised that the definition of the Clovis culture is to a degree ambiguous, the term being "used in a number of ways, referring to an era, to a culture, and most specifically, to a distinctive projectile point type", with disagreement between scholars about distinguishing between Clovis and various other Paleoindian archaeological cultures.
