HOLASPID VARIATION IN THE SOLENOPLEURID TRILOBITE PARASOLENOPLEURA GREGARIA (BILLINGS, 1865) FROM THE CAMBRIAN OF NEWFOUNDLAND
Bibliographic record
Abstract
Abstract: The Cambrian trilobite originally described as Bathyurus gregarius by Billings in 1865 is revised in the light of a new collection from what is judged to be its type locality in the Big Gully Marl Member of the Chamberlain's Brook Formation on the Cape St. Mary's Peninsula of south-east Newfoundland. Here assigned to Parasolenopleura gregaria, it is regarded as the senior synonym of Parasolenopleura cristata (Linnarsson, 1877) in the Swedish Paradoxides (Eccaparadoxides) insularis and P. (Plutonides) pinus zones, and Parasolenopleura lemdadensis Geyer, 1998 in the Moroccan Ornamentaspis frequens-Kymataspis arenosa zonal boundary beds. Among its features, important details of the relationships of the genal caeca to the eye and cephalic borders are given, as well as illustrations of the significant range of biotic and abiotic morphological variation in holaspid growth stages of the cephalon that will have some bearing on the revision of the Solenopleuridae.

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.
