5RT139.54 <br />Form: The specimen <br />irregular in <br />convex cross <br />the point of <br />of bifacial <br />Material: White chert. <br />is a small percussion flake • <br />outline, exhibiting a bi- <br />section. One edge, apparently <br />impact, features a portion <br />Flaking. <br />Dimensions: 1.22 cm long x 1.07 cm wide x .26 cm thick <br />Retouch: Bifacial retouch along one lateral margin <br />Functional <br />Interpretation: The presence of one edge of bifacial flaking <br />occurring at the proximal edge of the flake <br />indicates it to be a biface rejuvenation <br />flake. Wear on this proximal end is mani- <br />fested as edge rounding and step fractures. <br />SRT139.60 <br />Form: The specimen is the proximal portion of a <br /> biface. Bi-convex in cross section, the <br /> fragment exhibits straight lateral margins <br /> with a slight incurvate base. A11 edges • <br /> are heavily ground with the exception of <br /> those associated with the proximal snap <br /> fracture. <br />Material:. Fine-grained, light gray quartzite <br />Dimensions: 1.62 cm long x 1.98 cm wide x .57 cm thick <br />Retouch: Shallow parallel bifacial pressure flaking <br />Functional <br />Interpretation: As the tool is only the base segment of a <br /> blade, it is impossible to discern a function. <br /> However, it is characteristic of Paleo-Indian <br /> projectile points of the Plano tradition. <br />Cultural The base is typical of Plano tradition pro- <br />Affiliation: jectile points, during which Cody Complex <br /> occurs. Since the blade is absent, more <br /> specific identification is impossible. <br />• <br />40 <br />
