This is a rim to shoulder sherd of a cooking pot. The colors are not measured because they are highly mottled dark and light grays (on the interior) and grays, black, and some brown on the exterior, all suggestive of regular burning. The rim shape is unique. Triangular, with a point at the top, at the interior edge, and then a downward axis on the exterior to form another point, and then a third axis that joins the neck. New to typology. Should be drawn.
