Dibb, G. and C. Ellis - 1988 Madina Plano Points. Text of Original Publication follows. The stem edges and bases are usually ground. Fore-sections have slightly convex edges. Maximum point width occurs at or just above mid-point.
Surface flaking consists generally of a narrow, shallow, well-executed retouch.
It can range from a parallel to collateral patterned retouch to unpatterned in execution. Some points still retain remnants of broader thinning flake scars on their fore-section surfaces representing an earlier stage of manufacture. Blade and stem edges have had their shape regularized by a fine, intermittent retouch. Points are known on Onondaga, Collingwood, Balsam Lake, Gull River, Kettle Point and other, unidentified exotic chert sources. These points are highly restricted in range.
