LATE TORREJONIAN (MIDDLE PALEOCENE) MAMMALS FROM SOUTH CENTRAL ALBERTA, CANADA
Bibliographic record
Abstract
The Paskapoo Formation in central and south central Alberta, Canada, preserves continental sediments of Paleocene age. Outcrops of the formation on Nose Creek in northeast Calgary, at a locality called Who Nose?, have yielded fossil mammals from the middle part of the epoch. To date, some 400 dental specimens representing eight mammalian orders have been recovered, among them numerous well-preserved jaws. Newly named taxa include new species of Parectypodus and Baiotomeus (Multituberculata); new species of Parectypodus, Litomylus (Condylarthra), and Cyriacotherium (Pantodonta) are left unnamed. Biostratigraphic correlation indicates a late Torrejonian age for the local fauna based on the presence of the plesiadapid primate Pronothodectes matthewi. Faunal comparisons suggest a close similarity to the penecontemporaneous Gidley Quarry fauna, Montana, with a taxonomic diversity consistent with other co-eval faunas in the Western Interior of the United States. The specimens from Who Nose? constitute the largest collection of Torrejonian mammals from Canada, offering a unique perspective on mammalian diversity from an otherwise poorly represented interval in western Canada.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
