Dating of elko eared projectile points
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.
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.
Other operational criteria that have routinely been used to classify projectile points can also be estimated including: approximate Distal Shoulder Angles, possible Proximal Shoulder Angles, Basal Width/Maximum Width Ratios and Notch Opening Indexes.
Unfortunately the bases on all the point petroglyphs are obscured by the petroglyph representation itself – since they all are rendered as though they were hafted on foreshafts.
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.
Other examples of Coso Style petroglyphs are known outside that area including those in the El Paso Mountains, Panamint Mountains, Argus Range and north of the base at Centennial Springs. (a), (g), and (h) Little Petroglyph (Renegade) Canyon; (b) Darwin Wash; (c) Parish Gorge; (d) and (e) Sunrise Cliffs; (f) Sheep Canyon We were able to relocate all but four of the previously illustrated glyphs (see Grant et al. In visiting and relocating most of the projectile point petroglyph panels known to occur in the Coso Range, we identified a few more distinctive and even more realistically rendered elements not previously identified.Two types of glyphs are represented: isolated or individual projectile point images (19) and anthropomorphs with associated projectile point adornments (9).Tabulating the various types of glyphs, styles of projectile points and their locations provided the following observations.All anthropomorphs were adorned with points that were corner-notched.Most all depictions, whether isolated or with anthropomorphs, were corner-notched points.
