A fragmented projectile point, in Southern California archaeology terms, also known as an arrowpoint. The type is a Dos Cabezas serrated point (#12 from True's typology) from the Late Prehistoric period, 1300-800 years ago. This bifacial tool is an elongated triangle in shape. It is serrated along two edges and has a broken tip, perhaps due to impact. The base is concave. The haft element has two distinct tangs (end points) produced by side-notches for hafting. The stone material is volcanic glass, possibly Obsidian Butte, although only a few quartz inclusions are observed; the point is not glassy in sheen. It is fine grained and may be fire-affected.
It is fairly thick. The ventral side has bilateral flake scars. The dorsal side has a fairly central ridge down the length with bilateral flake scars. There is some evidence of retouch, or reworking noted within some of the serrated flake scars.
