<i>Clypeina</i>? <i>pamelareidae </i>n. sp., a new dasycladalean alga from the Upper Triassic of Lime Peak (Yukon, Canada)
Bibliographic record
Abstract
A new calcareous alga is described from the Norian limestones of Lime Peak, Yukon, Canada. The algae-bearing limestones were formed in a low-energy environment below the storm wave base, as indicated by the abundance of carbonate mud. Clypeina? pamelareidae n. sp. usually appears in the form of separate laterals scattered in the sediment. The laterals are pyriform, with the tip slightly curved upwards. Sometimes they are arranged around a non-calcified axial cavity. The lack of calcification of the connection between the main axis and the laterals led to the detachment and scattering of the latter in the sediment. The shape of the laterals and their arrangement are reminiscent of the genus Clypeina (Michelin). Still, the lack of completely preserved specimens leads us to attribute it with uncertainty to this genus. Almost certainly, the alga in question is individualised as a new distinct species, basically different from other Mesozoic or Cenozoic species of the genus, as well as from the only species of Clypeina known from the Triassic (Clypeina besici Pantic).

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.
