Abstract
Genus Shipingia Shen in Zhang et al., 1976 Type species. Shipingia hebaozhaiensis Shen in Zhang et al., 1976, from the Upper Triassic Ganhaizi Formation of Yunnan, China. Emended diagnosis. Carapace small or medium in size, rounded, oval or elliptical in outline. Dorsal margin long and straight, small umbo located at its anterior part. Growth bands wide in the upper part of the carapace, and narrow near the ventral margin. Growth bands near the umbo ornamented with irregularly arranged small and large sized reticulations. Growth bands in the middle part of the carapace ornamented with large sized reticulations in the upper part, and small sized reticulations in the lower part of each band. Growth bands near the venter ornamented with small sized reticulations. Locality and horizon. The middle Arnstadt Formation, the upper Stubensandstein Formation in Germany; the middle Groveton Member of the Bull Run Formation in Culpeper Basin, the Heidlersburg Member of the middle Gettysburg Shale Formation in Gettysburg Basin, the middle and upper Passaic Formation in the Newark Basin in the United States; the upper Blomidon Formation in the Fundy Basin in Canada; the Ganhaizi Formation in Shiping County of Yunnan Province, China. Remarks. In the original description of Shipingia Shen in Zheng et al., 1976 only large sized reticulations were mentioned on growth bands near the umbo. According to the new SEM micrography, small and large sized reticulations are irregularly arranged on growth bands near the umbo.

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.
