Three-Dimensional Morphology of <i>Beaconites capronus</i> from Northeast England
Bibliographic record
Abstract
Beaconites capronus is a winding meniscate backfilled trace fossil differentiated from comparable ichnotaxa Taenidium and Ancorichnus on the basis of its distinct and unornamented burrow lining. Typically, horizontal to subhorizontal B. capronus also includes vertical pipes, which serve as a point of entry for endobenthic deposit feeding activity. The burrows do not self-cross but often display secondary successive branching potentially indicating coprophagous feeding strategies in lower nutrient sediment. Beaconites capronus material is examined and discussed from the Carboniferous offshore transition zone deposits near Howick, United Kingdom. Samples were collected and analyzed using high-resolution serial grinding and modeling techniques documenting fine detail in three dimensions. As the burrows are actively backfilled and do not maintain a connection to the sediment water interface the trace making organism must have a method of coping with the low oxygen porewater conditions. Four methods are considered herein, as follows: 1) revisiting the sediment-water interface; 2) creating periodic shafts; or 3) employing the use of obligate anaerobic metabolism. Based on the material presented herein, an emended ichnospecific diagnosis is provided.

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.
