A giant beaver (Castoroides ohioensis Foster) fossil from New Brunswick, Canada
Bibliographic record
Abstract
An isolated incisor tooth of a giant beaver (Castoroides ohioensis Foster) recovered from Indian Island, New Brunswick, near the mouth of the Bay of Fundy, represents the most eastern record of this animal in Canada. Unfortunately no stratigraphic context is available for the specimen, which was recovered loose near a beach also known to yield archaeological materials. The specimen may have been deposited on a storm beach from near shore deposits, but it is also possible that the tooth was carried to the site by people. The rarity of giant beaver fossils in southern Canada adds to the significance of this specimen. RÉSUMÉ Une incisive isolée de castor géant (Castoroides ohioensis Foster) récupérée sur l’ile Indian, au Nouveau-Brunswick, près de 1'embouchure de la baie de Fundy, représente la trace physique la plus à l’est de la présence de cet animal au Canada. Malheureusement, on ne dispose d'aucun conlexte stratigraphique dans le cas de ce spécimen, qui à été récupéré sous une forme détachée près d'une plage également reconnue comme source d'objets archéologiques. La specimen pourrait provenir de dépäts littoraux et avoir été déposé sur une crête de temp&éte, mais il est aussi possible que des gens aient apporté la dent sur les lieux. La rareté des fossiles de castor géant dans le Sud du Canada rehausse Timportance de ce spécimen. Traduit par la rédaction

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.
