Jaws of a New Species of<i>Nanaimoteuthis</i>(Coleoidea: Vampyromorphida) from the Tuironian of Hokkaido, Japan
Bibliographic record
Abstract
A new Late Cretaceous vampyromorphid coleoid, Nanaimoteuthis yokotai sp. nov. is described on the basis of two lower jaws recovered from the Turonian of Hokkaido, Japan. The lower jaw of this new species consists of equally sized outer and inner lamellae, and the crest portion of the latter is wholly covered by the former. The maximum length of the outer lamella in the holotype attains 63.7 mm, suggesting a remarkably large body size of the living animal. The new specimens reported herein and other occurrences of cephalopod jaws and gladii which were previously described from Hokkaido (Japan) and Vancouver Island (Canada) demonstrate the existence of a comparatively highly diverse coleoid fauna including -in some cases exceptionally large- specimens of the Teuthida, Vampyromorphida, Cirroctopodida, Octopodida, and Sepiida in the Late Cretaceous North Pacific.
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.

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.
