Lithic Procurement and Provisioning at the Lower Palaeolithic Site of Shishan Marsh 1 in the Azraq Basin, Jordan
Bibliographic record
Abstract
Considerations of the landscape, the distribution and quality of resources, distances to outcrops, and proximity to other resources factor into the procurement decision-making by prehistoric foragers. However, the patterns of resource exploitation and utilisation are likely to vary by region, and those exhibited in marginal environments are not fully explored. This report focuses on the nature of lithic procurement and provisioning at the Lower Palaeolithic site of Shishan Marsh 1 in the Azraq Basin, Jordan. It draws upon several lines of evidence, including provenance and use-wear analyses performed on the biface assemblage. The results indicate raw material exploitation occurred at local and non-local distances to the site and the lithics were used for a variety of activities on medium-hard materials. Foragers moved toward the wetlands from significant distances on the surrounding landscape, likely bringing finished tools and, after use, discarding them in relatively good condition. The accumulation over time of ready-to-use tools at Shishan Marsh 1 points to a provisioning of the wetland margins for future needs.

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.
