Description of new materials of Ianthasaurus hardestiorum (Eupelycosauria: Edaphosauridae) and a re-evaluation of its phylogenetic relationships
Bibliographic record
Abstract
Ianthasaurus hardestiorum, a basal edaphosaurid from the Upper Pennsylvanian of Garnett, Kansas, has been described on the basis of two incomplete, juvenile specimens and a series of disarticulated vertebral elements. New material of this poorly known species includes previously unknown bones and increases knowledge of the anatomy and variation in this taxon. The complete ossification of the neural arches and the overall larger size of the vertebrae relative to those previously described suggests that they were part of an adult individual. Tooth morphology in the marginal dentition more closely resembles that seen in the genus Edaphosaurus. Phylogenetic analysis of edaphosaurid synapsids supports the hypothesis that Ianthasaurus is the sister taxon of all other members of the clade. However, the incomplete fossil record of other referred edaphosaurids such as Lupeosaurus and Glaucosaurus makes full resolution of their phylogenetic interrelationships difficult to assess.

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.
