A new genus of Triassic actinopterygian with an evaluation of deepened flank scales in fusiform fossil fishes
Bibliographic record
Abstract
Revision of the genus Peltoperleidus leads to recognition of a single persisting deepened scale row as the main diagnostic feature for the newly established genus Allisolepis gen. nov. The counts of deepened scale rows are taken to be very consistent in all species assigned to Peltoperleidus and Allisolepis gen. nov., since they can be perfectly matched with skull bone patterns and counts of lepidotrichia. An initial evaluation shows that presence and array of variably deepened flank scales in fusiform fossil fishes have previously been underestimated in terms of their occurrence and as a putatively phylogenetic signal: the counts of deepened flank scales show some negative correlation with body size in fusiform fishes up to a certain standard length only, and occur predominantly in smallest fishes in the Middle Triassic. No significant correlation exists between scale row counts and standard length with respect to taxonomy; although interrelationships of these actinopterygians are still poorly understood, it appears likely that similar patterns of deepened scale rows may have developed independently during the Early-Middle Triassic.

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.
