Description
The specimen exhibits a medium-sized, ovoid morphology with an elliptical profile. Its blade is characterized by a broad, excurvate shape, with the maximum width occurring between the midpoint and lower third of the point. The base of the point is subtly convex, featuring rounded corners that soften its overall outline. The flaking pattern observed on this artifact is random, lacking a discernible, organized arrangement.
