Description

This artifact exhibits a robust, irregular morphology, with outlines that can fluctuate between oval and triangular forms. In cross-sectional profile, it displays a varied geometry, spanning from a curved, bi-convex ellipse to a more angular, plano-convex shape. The blade's formation is attributed to percussion flaking, characterized by a pronounced, steep angle of flake removal, typically falling within the range of 55 to 85 degrees.
