Abstract
The accuracy of the taxonomic assignment of three skulls in the collections of the Museum of Comparative Zoology (Harvard University) to the Early Permian taxon Tersomius texensis has been called into question. Here, we re-evaluate the holotype of T. texensis and the three MCZ specimens within the context of discoveries made over the last few years. The results of our phylogenetic analyses corroborate our morphological assessments, revealing that only one of the three skulls (MCZ 1912) is assignable to T. texensis. We identify MCZ 1415 as Pasawioops cf. P. mayi, otherwise known only from Oklahoma, and MCZ 1911 as a new genus and species of dissorophid. Study of the three MCZ skulls reveals previously unrecognized diversity of temnospondyls in the coastal fauna represented in the Archer City Formation of Texas. La précision de l’attribution taxonomique de trois crânes dans les collections du Museum of Comparative Zoology (université de Harvard) à un taxon du Permien inférieur, Tersomius texensis, a posé question. Ici, nous réévaluons l’holotype de T. texensis et les trois spécimens MCZ dans le contexte des découvertes effectuées ces dernières années. Les résultats de nos analyses phylogénétiques corroborent nos estimations morphologiques, à savoir que seul l’un des trois crânes (MCZ 1912) est attribuable à T. texensis. Nous avons identifié MCZ 1415 comme étant Pasawioops cf. P. mayi, par ailleurs, déjà connu dans l’Oklahoma, et MCZ 1911 comme étant un nouveau genre et une nouvelle espèce de dissorophidé. L’étude de ces trois crânes révèle une diversité, non reconnue précédemment, des Temnospondyles dans la faune côtière de la formation Archer City au Texas.

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
