| Comment | most of the found material belonged to the first stages of roughing and shaping out preforms, the rest was exhausted cores, striking platform openings, tablets, crests, lateral and rarely fragments of central blades, also unsuitable preforms. All blades were produced using bifacial preforms, precisely shaped out. Dimensions of primary platform openings variable, but often close to the roughout's dimension; secondary platform openings fit closely to the size of the exploited cores or broken preforms. estimated size of roughout at the beginning of the shaping out: 18 cm long, ca. 10 cm wide, no more than 5 cm thick; Bi-directional blade production: to produce regular pointed blades with a trapezoid basal section and a triangular distal section, ca. 15 cm long and 15 mm wide --> very high quality and standardization, therefore very qualified knappers with know-how; chaine opératoire: 2 opposed striking platforms are opened on the preforms; they are inclined towards the posterior rectilinear crest; striking platforms used for detachment of the central pointed blade or the detachment of two long lateral blades to predetermine the point morphology; also used for the extraction of short lateral blades to maintain the convexity of the debitage surface. after the opening, the blade production starts with the detachment of the frontal crest from the first platform, then another one detached from the second platform; then, 2 lateral blades slightly inclined towards the sides of the core are extracted from the second platform, then a central pointed blade is extracted from the first platform; then a central upsilon blade is extracted from the 2nd platform to correct the longitudinal rectitude of the debitage surface; the major elements are prepared with the detachment of lateral blades (short and twisted), and they are prepared with an intensive abrasion of the overhang (removals done with a hammerstone). No more than 7 pointed blades can be produced like this from one core. Then, these pointed bladelets were taken out if the workshop. Prismatic Blade Production: serial extraction of bladelets by using the pressure technique, more than 75 mm long, 11 mm wide, 3 mm thick; also executed on bifacial preforms, the cores show well executed posterior crests with an alternating bifacial treatment (little more convex than the crest of naviform cores and slightly larger); the platforms are flat and inclined towards the posterior crest. 50 - 60 bladelets were obtained from each core. Other finds in Area P: retouched pieces (rare): side scraper, borer, burin, utilized blade, arrow heads (e.g. Abu Gosh); imported obsidian from Nenezi Daği and Kayırlı. |
