Late Ordovician cornulitids from Anticosti Island, eastern Canada, and their evolutionary implications
Bibliographic record
Abstract
Abstract Two Late Ordovician cornulitid species, Cornulites richmondensis (Miller, 1874) and Cornulites hemistriatus new species, from the Ellis Bay and Vaureal formations of Anticosti Island, eastern Canada, are each shown in this study to have a thick, punctate, cross-bladed lamellar, calcitic conch wall, a crested fold, a septate juvenile part, and endoconic chamber deposit. These Late Ordovician, free-living (i.e., nonencrusting) forms of Cornulites Schlotheim, 1820 have characters intermediate between Cornulites and the late Silurian-Devonian forms of Tentaculites Schlotheim, 1820, particularly by having incipient inner layers and poorly fused annuli, but lacking cornulitid-type vesicular microstructures. The described cornulitids are similar to brachiopods in their cross-bladed lamellae and pseudopunctae, but their lamellar layers are considerably finer and much less distinct than those of brachiopod shells.

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.
