Systematic contribution of the auditory region to the knowledge of the oldest European Bovidae (Mammalia, Ruminantia)
Bibliographic record
Abstract
The ear region has a strong potential for evolutionary studies. While the petrosal bone suffers from ontogeny and allometry, the bony labyrinth provides crucial information for phylogeny. The study of the bony labyrinth itself allowed for argumentation of the early bovid species Eotragus artenensis and Eotragus clavatus being closely related, while a newly described species and genus of early Bovidae from Montréal-du-Gers (France), formerly attributed to Eotragus, clearly belong to another lineage. The morphology of the bony labyrinth of these oldest bovids confirms that Eotragus is a stem Bovidae, while the new Bovidae is more derived. Since the bony labyrinth is a structure that is little affected by ontogeny, allometry, and sexual dimorphism, we propose this structure and its surrounding petrosal bone as the holotype for this new species. This study shows the importance of the ear region in the context of micro- and macro-evolution.

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.
