Late Pleistocene Faunal Assemblages from Karst Cave Settings on Northern Vancouver Island, Canada
Bibliographic record
Abstract
We present the results of our investigations in karst caves on northern Vancouver Island. This work focuses on late Pleistocene faunal remains and potential archaeological deposits. Our analyses of faunal remains from these caves reveal that a variety of animals have inhabited the region since the Last Glacial Maximum. Pleistocene taxa recovered include black-tailed deer (Odocoileus hemionus), black bear (Ursus americanus), mountain goat (Oreamnos americanus), Vancouver Island marmot (Marmota vancouverensis), wolf/dog (Canis spp.), weasel (Mustela), and frog (Anura). We also report on a previously undescribed diminutive red fox (Vulpes vulpes) which no longer inhabits Vancouver Island. We present the results of sedaDNA analysis of cave sediments which demonstrates promise in supporting the morphological identification of animal remains. The results of this study, combined with previous research, help to constrain the timing of the Last Glacial Maximum and when land became viable to support land mammals on northern Vancouver Island.

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.
