Abstract
The end-Permian extinction event is regarded as the most severe of the five major extinction events in the history of life. Recent work in the Karoo Basin of South Africa suggests that the extinctions at the Permo-Triassic boundary (PTB) may have been followed by a second pulse of extinctions, one that claimed the few species that crossed the PTB and thus survived the first extinction pulse. We report here a new specimen of the procolophonoid reptile, Sauropareion anoplus, which was known heretofore only from a single specimen from Lower Triassic strata of the Palingkloof Member, Balfour Formation. The new specimen comes from the lower part of the overlying Katberg Formation and serves as the last appearance datum for the stratigraphic range of S. anoplus. It indicates that S. anoplus survived the second pulse of PTB extinctions and reinforces the hypothesis that procolophonoid evolution was not seriously perturbed by extinctions that mark the beginning of the Triassic Period.

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
