A High-Latitude Dromaeosaurid, 'Boreonykus Certekorum', Gen. Et Sp. Nov. (Theropoda) from the Upper Campanian Wapiti Formation, West-Central Alberta
Bibliographic record
Abstract
Dromaeosaurids were rare components of most Late Cretaceous terrestrial ecosystems and are poorly known from high palaeolatitudes. New dromaeosaurid material, including a frontal and associated postcranial elements, is described from a dense monodominant ceratopsid bonebed on Pipestone Creek, near the city of Grande Prairie (Unit 3, Wapiti Formation, upper Campanian), central-western Alberta, Canada. This stratigraphic interval is significant because it records a period of terrestrial deposition at a time when much of the western interior of Canada and the United States was inundated by the Bearpaw Sea. A phylogenetic analysis recovers 'Boreonykus certekorum', gen. et sp. nov., as a derived eudromaeosaur, possibly within Velociraptorinae. The identification of a new dromaeosaurid from the Wapiti Formation simultaneously helps fill an important gap in the record of late Campanian dromaeosaurids, bolsters support for a partly endemic fauna within the Wapiti Formation, and potentially adds to the North American record of a predominantly Asian Velociraptorinae.

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; both teacher heads agree on what is shown here.
