Bibliographic record
Abstract
Bradyfallotaspis coriae n. sp. (Fig. 3.1–3.6) Type material. Holotype PWNHC-2009.20.1. Paratypes KUMIP 320696-320700 and PWNHC-2009.20.2- 2009.20.8 from Nevadella zone, Early Cambrian, Sekwi Formation, Mackenzie Mountains, Northwest Territories, Canada (Section 2, 345– 375 m above base of formation and in float; Section 14 in float). There are a total of 13 specimens. Etymology. Named in honor of Corinne Myers, University of Kansas, for her assistance with laboratory techniques that facilitated the completion of this research. Diagnosis. Anterior cephalic border (sag.) equal to length (sag.) of LO; preglabellar area present; ocular ridges connected to glabella at L3; ocular lobes in contact with posterior border furrow; LO spine present in some specimens. Description. Width of cephalon (tr.) is greater than or equal to twice the cephalic length (sag.); anterior cephalic border length (sag.) is approximately equal to or slightly less than the length (sag.) of LO; preglabellar field is present; width (tr.) of the extraocular area is approximately 1.5 times the width (tr.) of the interocular area; a strongly incised SO is present (when preservation allows determination); a small spine or node is present on the posterior margin of LO in some specimens. Discussion. This species can be distinguished from B. sekwiensis by its relatively narrower (sag.) anterior cephalic border and by its possession of a preglabellar area. It differs from B. patula, B. nicolascagei, and B. sekwiensis by possession of ocular lobes in contact with the posterior border furrow. Several specimens (Fig 3.3 and 3.6) are smaller and relatively narrower than typical specimens of B. coriae, yet they possess key diagnostic features such as ocular lobes that contact the posterior border furrow, a preglabellar field, and ocular ridges connecting the ocular lobes at the posterior lateral margin of LA (although not as prominently as in larger specimens). These may be earlier ontogenetic forms of B. coriae and are treated as such in this paper.
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.
