The Cambrian (Furongian) olenid trilobite <i>Peltura</i> from Avalonian Nova Scotia, Canada, with a review of some species from Baltica
Bibliographic record
Abstract
The Cambrian olenid trilobite Peltura Milne-Edwards, 1840 is widespread in the Furongian strata of the Cambrian continents of Baltica and Avalonia, and has played a significant role in biostratigraphic zonations for both regions. Despite this importance, the genus is poorly known in Avalonian Canada. New collections from the Chelsey Drive Group on Cape Breton Island, Nova Scotia, yielded numerous sclerites of a new species, Peltura hutchinsoni sp. nov., that may also occur in the Parabolina lobata Zone of Baltica. Archival specimens from Sweden and Norway allow the revision of Peltura scarabaeoides ( Wahlenberg, 1821 ) and Peltura acutidens Brögger, 1882 , respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
