Abstract
FIGURE 8. Location of significant fossil specimens collected within Bonebed 190 horizon. A, overview of BB190 host horizon within Rhythm 4; 'BB190' point marks original quarry stake marked in 2002; 'BB190A-C' and 'BB303' points mark fossil-rich localities discovered during this study. Coordinates in WGS84 / Universal Transverse Mercator zone 12N, EGM96 geoid. B, location of significant fossil specimens along BB190 horizon at base of Rhythm 4, projected on perspective render of digital outcrop model. C, complete left hadrosaur dentary collected in 2023 near eastern edge of Amphitheatre, ~8m above main BB190 horizon; photo courtesy of Andre Mueller. D, fused tyrannosaur nasals collected in 2023 about halfway between BB190 original quarry height and BB303 quarry height. E, bowfin (family Amiidae) dentary collected in 2022 at BB190A quarry, 10 cm above main bonebed horizon; photo courtesy of Hans Larsson. F, centrosaurine ceratopsid nasal horn core with premaxilla collected in 2018 at BB190C quarry, at northwestern edge of Amphitheatre. G, ceratopsid (cf. Styracosaurus) parietal fragment found ex situ in 2019 near BB190 microsite.

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.
