LATE PLEISTOCENE LEMMINGS (LEMMUS TRIMUCRONATUS AND DICROSTONYX GROENLANDICUS; MURIDAE: RODENTIA) FROM ALBERTA, CANADA
Bibliographic record
Abstract
A gravel quarry near Edmonton, Alberta, Canada, yielded remains of micromammalian taxa not previously reported in the mid-Wisconsinan (late Pleistocene) interstadial “local fauna.” A left M1 and an upper incisor fragment of Lemmus trimucronatus and a left M2 of Dicrostonyx groenlandicus were recovered. These finds represent the 2nd Pleistocene record for Lemmus in Alberta, the 3rd for Dicrostonyx, and the 1st for both taxa from a northern Great Plains site. They help to fill distributional gaps between Beringia and the midcontinent. In association with those of large grazing megaherbivores, these new arvicoline finds support the inference of a cool, fairly dry steppe in central Alberta during the last interstadial.
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.
