LATE ORDOVICIAN AND SILURIAN LICHID TRILOBITES FROM NORTHWESTERN CANADA: EIGHT NEW SPECIES FROM SUBFAMILIES LICHINAE, PLATYLICHINAE, AND TROCHURINAE
Bibliographic record
Abstract
Eight new species of lichid trilobites representing five genera in three subfamilies, from the Avalanche Lake area of the southern Mackenzie Mountains, Northwest Territories, Canada, are described. The subfamily Lichinae is represented by Dicranopeltis n. sp. and the subfamily Platylichinae by the early Llandovery Platylichas infimus n. sp. The subfamily Trochurinae is represented by six species belonging to four genera. These are Acanthopyge (Lobopyge) sp. (Wenlock), the earliest known species of the genus Acanthopyge and subgenus Acanthopyge (Lobopyge), A. (L.) pristina n. sp. from the Glyptograptus persculptus Zone in the latest Ordovician, Dicranogmus lepidus n. sp., D. wilsoni n. sp. (both Wenlock), Dicranogmus n. sp. (Llandovery), and Radiolichas guttatus n. sp. (Wenlock).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
