Petrosal and Basicranial Morphology of Leptoreodon major (Protoceratidae, Artiodactyla)
Bibliographic record
Abstract
Leptoreodon is a basal member of the Protoceratidae, an extinct group of artiodactyls variably allied with the Camelidae and the Ruminantia. The basicranial morphology of other protoceratids (Leptotragulus, Protoceras, Syndyoceras) is similar to that of ruminants, supporting the hypothesis that the two clades are closely related. However, study of the basicranium of Leptoreodon major has revealed that protoceratid basicranial morphology is more variable than previously thought. Leptoreodon does share morphological features with some, if not all, other protoceratids, but the taxon also has some features not previously documented in the family. These previously undocumented features resemble the basicranial morphology of camelids rather than ruminants, suggesting that previous hypotheses of protoceratid relationships need to be reexamined.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
