Excelsior Ovoid
Cluster: Coastal Contracting Stem Cluster Description of Physical Characteristics and Flaking Pattern:
This is a medium to large ovoid contracting stem point with an elliptical cross section. The blade is excurvate, curving in at the tip and back in at the shoulders edge. Serrations are common on this point. The shoulders are weak to absent with a contracting stem. This point commonly has a leaf appearance with no notable difference where the blade meets the hafting region. The base is convex. This type is made using primary percussion flaking then subsequent pressure flaking to finish the blade and stem with a flaking pattern most commonly random, but may range to chevron or oblique.
