Abstract
PROTOCYPRAEA? SP. 1 FIGS. 5P, 6A–C Eocypraea sp. Williams et al., 2018: unnumbered fig. Hypotype— CDM 997.91.3 (figs. 5P, 6A–C), length 48.1 mm, width, 31.4 mm, height 25.3 mm, height. Informal locality AP3 (J.W. Haggart, personal communication, 2022). Occurrence— Questionably late Paleocene (Thanetian Stage), central east coast of Vancouver Island, British Columbia, Canada. Oyster Bay Formation (“Appian Way beds”), approximately 45.5°N, intertidal area on east coast of Central Island District, Vancouver Island, British Columbia, Canada. Description— Shell moderately large, smooth, turnipshape, base narrow, aperture narrow, dentition relatively small size. Shell tapers rapidly anteriorly; anterior part of shell somewhat projected. Shell with maximum width posterior to center of shell, but very inflated posterior area incomplete showing only small depressed area (only base of spire present) with sunken sulcus area. Aperture is moderately wide and fairly straight, with some bending in posterior area. Outer lip shows numerous relatively small-sized teeth anteriorly. Inner lip similar, except for the teeth being smaller and not extensive. Remarks— Only a single specimen (possibly a juvenile) is known. It is nearly complete, except for most of the broken-off posteriormost part of the shell, thus precluding the assignment of this unnamed specimen. This specimen, which is the northernmost occurrence of a Paleogene cypraeoidean in the NEP region, is like no other NEP Paleogene cypraeoidean, nor like any NEP Late Cretaceous specimen. A manuscript currently in preparation by J.W. Haggart et al. will further document this so-called “Appian Way fauna” [presumably of late Paleocene age and contemporaneous with the “Oyster Bay Formation”], Central Island District, Vancouver Island, British Columbia, Canada. McLachlan and Pospelova (2021) presented dinoflagellate data for an early Paleocene age of the “Oyster Bay Formation,” but that age is in contradiction to late Paleocene to middle Eocene ages variously based on plants, sporomorphs, marine mollusks, decapods, and shark teeth (see McLachlan and Pospelova 2021 for a review of this literature).

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.
