THE UPPER CAMBRIAN TRILOBITE STENOPILUS: MORPHOLOGY, MODE OF LIFE
Bibliographic record
Abstract
Abstract Previously unstudied and earlier-known specimens have revealed the wide cephalic doublure and median ventral suture in Stenopilus; the hypostome is unknown but was probably natant. The cranidium of S. pronus differs from that of the type species S. intermedius in its greater length and convexity; the pygidium is known from rare complete specimens. These two species are present in Quebec, Newfoundland, and Vermont. They are differentiated from Leiocoryphe, which also had a highly effaced cephalon. Relationships remain problematic between these two genera and others currently placed in Plethopeltidae. An enrolled specimen of S. pronus is refigured and the anatomy and mode of life considered as that of a vagrant benthic animal rather than one that lived in a burrow as previously thought.
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.
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.
