Description
This triangular point exhibits a distinctive morphology, characterized by a stem that broadens towards the base, although occasional specimens may display a straight stem. The cross-sectional profile is compressed, lending a flattened appearance to the point. The blade edge is generally straight, yet may exhibit subtle variations, ranging from a slight outward curve to a gentle inward curvature. The shoulders are marked by pronounced barbs, terminating in sharp or pointed tips. The basal edge is variable, spanning a range from straight to gently convex. The flaking pattern observed on this point is random, lacking a discernible order or sequence.
Size
The arrowhead's dimensions are as follows: it measures between 17 and 57 mm in overall length, with a stem length ranging from 4 to 6 mm. The blade's width spans 10 to 19 mm, while the neck width varies between 3 and 6 mm. The basal width is recorded at 5 to 8 mm, and the thickness of the arrowhead falls within the range of 3 to 6 mm.
Distribution
