A New Species of Pantylid ‘Microsaur’ from the Carboniferous of Nova Scotia and Implications for its Ecology
Bibliographic record
Abstract
Microsaurs' are a group of terrestrial, limbed vertebrates unearthed in North America and Europe, spanning the Late Carboniferous to the Early Permian.Once considered monophyletic, recent studies have revealed their polyphyletic nature, necessitating further investigation into the relationships within this diverse early tetrapod group.A recently discovered, near-complete 'microsaur' skull (NSM 017GF020.002)from Sydney Mines Formation of Nova Scotia fuels this inquiry.Utilizing micro-CT scanned data, I present a full description of the anatomy, investigate its phylogenetic relationship with other "microsaurs", and explore the possible ecological role and diet by comparing its dental morphology with extant reptiles.The morphological disparity of NSM 017GF020.002with other pantylids, coupled with phylogenetic analysis results, support the recognition of a new genus and species.Its unique palatal dentition not only provide strong evidence rooting the origin of herbivory in Late Carboniferous, but also showcase considerable diversity within the family Pantylidae.method and attempt to compare its values to those from a living reptile dataset in order to infer the diet of the animal.

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.
