Abstract
METAMYNODONTINI The tribe Metamynodontini is defined by three unambiguous synapomorphies free of homoplasy (Bremer index = 1): the zygomatic arch is high 11 (1); the postglenoid process of squamosal is flat 42 (0); the humerus distal articulation has a deep median constriction (diabolo-shaped) 194 (1). This tribe includes the two clades (Paramynodon, Megalamynodon) and (Sellamynodon, Metamynodon). The clade formed by Paramynodon and Megalamynodon is supported by two unambiguous synapomorphies (Bremer index = 1): the zygomatic process progressively diverges from the maxilla 37 (0); I3 has a similar size to I2 293 (1). The clade formed by Sellamynodon and Metamynodon is supported by a single unambiguous synapomorphy (Bremer index = 1): the external auditory pseudomeatus is closed 18 (2). The specimen UNISTRA.2015.0.1106 is sister group to Metamynodon planifrons, which supports its taxonomical identification (Bremer index = 1). Metamynodon planifrons (sensu lato, = UNISTRA.2015.0.1106 and M. planifrons) has three autapomorphies: the anterior base of the zygomatic process of the maxilla is low 10 (1); the vomer is acute 38 (0); the paracone fold of M3 is absent 289 (1).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
