Morphological Analysis of the Bone Serrated Points from Early Neolithic Complexes of Shamanka 2 Burial Ground
Bibliographic record
Abstract
An analysis of the bone serrated points from the burial complexes of Shamanka 2 burial ground is presented. The origin of the collection makes it “ritual”, which may explain the large number of undamaged items. Several spikes have been broken intentionally at the time of their interment. Supposedly, several points have been specifically made for interment. In accordance with the morphological analysis, we have identified two groups of serrated spikes: (I) detachable tools and (II) non-detachable tools. Differences in structural elements of the stopper-line determine 7 types of harpoons (95 items), and variations in base structure define 2 types of points of leisters, javelins, spears etc. (6 items), while 15 fragments of blade were excluded from the analysis. Harpoons of the Type I-1 and Type I-2 are divided into 9 varieties, in accordance with structural elements of the blade. Harpoons of the Type I-3 are divided into 2 subtypes due to differences in structural elements of the shaft. Harpoons of the I-4 – I-7 types are represented by only 1 item for each type and are considered to be individual tools. Group I (harpoons) consist mostly of tools with an orifice for line lashing (89 items). Harpoons that feature stopper-line structural elements without through hole are represented here by only 6 items. II-2 type points with a unilaterally beveled base represent most non-detachable barbed tools – 5 items. II-1 type points with a wedgelike base (in a profile) consist of only 1 item. The designated types and varieties of Shamanka II cemetery barbed spikes correlate with items from different synchronous and asynchronous sites of both bordering and substantially remote regions. Serrated points are found mainly in male burials but absent in children's burials. Chronologically, 111 barbed spikes relate to the Phase 1 of the Shamanka 2 cemetery functioning. Five more spikes were recorded in 3 burials of the Phase 2. Barbed spikes of the chronological Phase 2 are represented with 4 items of the I-1.4 variety from burials No. 108-1 and 64-2, as well as 1 item of the I-2-1 variety from a grave No. 49. The last artifact probably represents an ideal model of two-row harpoons with symmetrically situated barbs and a sword-like spike. Harpoons with a curved blade (Type I-1.4) were registered only in burials of the chronological Phase 2. The barbed spikes of the I-1 and I-2 types, which feature a stopper-line with through holes and lateral projections, correlate with a definition of harpoons of the Kitoi type.

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.
