Radiocarbon dates for the early shouldered Tardigravettian from the rockshelter of Chinchon 1 at Saumane-de-Vaucluse and the chronology of the recent Provençal Upper Palaeolithic
Bibliographic record
Abstract
The lithic industry with shouldered points and truncated backed bladelets from the rockshelter of Chinchon 1 in the Vaucluse has been variously interpreted over the past few decades : some authors clearly see it as belonging to an ultimate, classic, phase of the final Magdalenian, whereas others link it just as clearly to an early, Italic, phase of the Tardigravettian. The results of stratigraphic, sedimentological and palaeontological analyses speak for an early date for this complex, a date that had hitherto eluded absolute dating. Here we present a series of new chronological markers for this episode, subjected to Bayesian analysis and modelling. We examine the chronological relationship between these new data and the Salpetrian Tardisolutrean of Languedoc as well as the recent phase of activity in Cosquer Cave and show that the (early) Salpetrian Tardisolutrean and early Tardigravettian with shouldered points are partly synchronous ; further, that in the Tardigravettian region where Cosquer Cave is located, it is in the early phase of the Tardigravettian with shouldered points that the paintings and engravings of the second period of activity at Cosquer were created.

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.
