Abstract
In the Late Triassic of Petrified Forest National Park (PEFO), AZ, the coincidence of high-precision geochronology and robust lithostratigraphy allows an adaption of the Bayesian statistical approaches of Haslett and Parnell (2008) and Alroy (2014) to quantify the dynamics of a Late Triassic vertebrate extinction and replacement, the Adamanian-Revueltian (A-R) faunal turnover. This analysis indicates negligible probability of synchroneity of Adamanian extinctions and Revueltian originations. This protracted reconstruction of the A-R turnover decouples the event from the geologically instantaneous Manicouagan impact (215.4 + 0.20 Ma; Québec, Canada), previously implicated as a causal mechanism.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
