Basal Double Tang Point

This triangular point features a medium-width stem and an elliptical profile. Initially, the blade exhibits a pronounced excurvate shape, although repeated resharpening can transform it into an incurvate form. The shoulders are distinguished by barbed tips, while the stem remains straight. A notable characteristic of the base is the presence of a deep, central basal notch that spans the entire length of the stem, creating the illusion of dual stems. The flaking pattern on this point is randomized, lacking a discernible order or sequence.

The dimensions of the arrowheads are as follows: they range in overall length from 25 to 55 mm, with stem lengths varying between 5 and 8 mm. The width of the blade spans 28 to 50 mm, while the stem width at the shoulders measures between 23 and 25 mm, based on a limited dataset.

This type is mainly discovered in Zacatecas, Mexico and extends into western Texas and southern New Mexico with diminishing occurrence.
