Terminal-Edge Knapping Techniques in the Final Sartanian Complexes of Baikal-Yenisei Siberia
Bibliographic record
Abstract
The article presents the characteristic of the terminal-edge microknapping from the archaeological complexes of the Final Sartanian (sr4 ) of Baikal-Yenisei Siberia. These complexes are dated in the interval of 14.7– 12.8 ka cal BP. Most of them are localized in the Southern Angara region (14 objects). The rest of them are located on the Upper Lena (1 object) and in the Kan-Yenisei region (2 objects). Cultural complexes from the above-mentioned interval are included a large number of the Bølling–Allerød (BA) soils. The process of the identification of techniques/methods of terminal-edge microknapping coincide with understanding that is considered in Japanese archeology. Variations of the Yubetsu techniques (Sakkotsu, Oshorokko) are widely used including those which have a sharp flaking angle in the traditional system of frontal platform trimming. Bifaces, unifaces, flakes, platy partings and pebbles were the preforms. There are single forms made in the Rankosi technique. The earlier technique of Saikai continues to exist. The blanks were pebbles, flakes, specially prepared forms, bifaces. The main feature of this technique is the trimming of the platform by transversely oriented spalls with one of the laterals. It is combined with Campus technique. It is based on the use of flakes, flattened cores of various modifications and specially prepared bifacial forms as blanks. For the Campus technique a special variant of platform trimming was fixed which was formed by a series of flakes from the lateral as in the Saikai technique. Then the working segment of the platform was supplemented with a specific “stepped” flakes from the front. The closest analogies of the Yubetsu strategy are found in the materials of synchronous objects in the Baikal-Patom highlands and Western Transbaikal region. The combination of the specific techniques of microknapping of the Saikai and the Campus has broad analogies in the Sartanian complexes of the Yenisei River valley. In the development of the cultures of the late stage of the Upper Paleolithic of Baikal-Yenisei Siberia a certain continuity is traced. It is expressed in the development of microknapping strategies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
