The dates provide a general age range for these corner notched and basal notched point depictions.
The age is consistent with the well documented and radiocarbon supported ages for Elko Series dart points and Humboldt Basal Notched thrusting spears, knives and dart points.
All anthropomorphs were adorned with points that were corner-notched.
Yet even with the latter condition, the isolated examples contain no side-notched specimens.
The points adorning the anthropomorphs might lead us to think they might represent side-notched points as they do contain rather incurvate edges.
This rare occurrence has only been documented at a few archeological sites in North America (Callahan 2003; Keyser and Klassen 2001; Riggs 2001; Sutherland and Steed 1974; Thomas and Thomas 1972).
Campbell Grant and his associates initially recognized a number of such projectile point petroglyphs within the Coso Range rock art tradition (Grant et al. The authors mention them briefly and only devote a single paragraph within their 147 page monograph.
CLASSIFICATION OF POINT STYLES Three broad categories of projectile point forms are commonly recognized in the Great Basin: shouldered, side-notched and corner-notched (Thomas 1981).
Although no true metrics are available for the Coso point petroglyphs (such as the actual length, width, thickness or weight of the artifacts they represent), it is possible to estimate from the glyph outlines their gross general morphology.Both figures are either animal-human or human hunter (shamanistic? Alternative suggestions are included for understanding this apparent paradoxical relationship of male weaponry with the feminine gender.The depiction of realistic renderings of projectile point forms is an unusual feature at a handful of prehistoric rock art sites in the United States.However, even after mentioning them and providing pen and ink sketches of these elements and figures they did not attempt to date them.Neither did they comment on the character of the figures or their possible meaning and function of the images of the projectile points themselves.Most of the points recognized would be classified as corner-notched forms.
