Anatomy and revised diagnosis of the embolomere <i>Calligenethlon watsoni</i> from Joggins, Nova Scotia, based on micro-computed tomography
Bibliographic record
Abstract
Abstract Although Calligenethlon watsoni, an enigmatic embolomere from Joggins, Nova Scotia, has been known since 1934, an in-depth description of its anatomy (including CT data) and updated taxonomic diagnosis has yet to be completed. Additionally, subsequently discovered embolomere specimens have been referred to the taxon simply if they display embolomere traits. As a result, Calligenethlon is represented by a collection of specimens united on the basis of largely non-diagnostic traits. Here, the exquisitely preserved specimen identified as Calligenethlon, NSM 994GF1.1, is described in detail using micro-computed tomography. Comparison of this specimen to the holotype supports its referral to Calligenethlon and the anatomical knowledge gained here allows for the generation of a more robust morphological diagnosis of the genus Calligenethlon. We then re-evaluate all other referred specimens to determine which are consistent with their referral to the taxon, and which are inconclusively referred to the taxon. These data are discussed as they provide new insights into the anatomy of Calligenethlon and the diversity of embolomeres at the Joggins’ locality.

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.
