Dating of elko eared projectile points
All anthropomorphs were adorned with points that were corner-notched.
Most all depictions, whether isolated or with anthropomorphs, were corner-notched points.
Therefore we believe those dart point depictions and XRF dates place the Coso projectile point drawings during a range of time from about 2000 BC to AD 1.
The latter age range is synchronous with the a period of dart and atlatl use and is coterminous with the earliest accepted dates for the initiation of Rose Spring Series arrow points (ca. Also some surprising new observations associate the feminine gender with at least two of the projectile point petroglyph images.
Assuming that the points depicted do not have concave bases, they would appear to have basal indentation ratios near 1.0.
The basal width / maximum width position we would estimate at 0.0 and the maximum width position is 0%.
Two types of glyphs are represented: isolated or individual projectile point images (19) and anthropomorphs with associated projectile point adornments (9).
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.Most of the points recognized would be classified as corner-notched forms.Corner-notched points occurred both as isolated images and in conjunction with pattern bodied anthropomorphs.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.
