Diablo Corner Notch Point

This triangular point exhibits a distinctive morphology, characterized by an expanding stem that tapers to a corner notch. Its cross-sectional profile is elliptical and relatively thin. The blade's curvature varies from slightly excurvate to straight, with the maximum width occurring just superior to the shoulders. The shoulders themselves display a range of orientations, from horizontal to inclined. The stem, which expands towards the base, features a margin that can be either straight or subtly concave, with basal corners that are rounded. Fabricated from a slender flake, this point was completed using pressure flaking of mediocre quality, resulting in a flaking pattern that appears random and lacking in uniformity.

The dimensions of the arrowheads are as follows: they range in length from 24 to 30 mm, with a blade width spanning 22 to 28 mm, and a thickness of 4 to 7 mm, based on an analysis of a limited dataset.

This variety has been discovered in Diablo Canyon within the Sierra de Tamaulipas region of Mexico.
