Early Albian (Early Cretaceous) douvilleiceratid ammonites from Haida Gwaii, British Columbia, Canada
Bibliographic record
Abstract
Abstract The early Albian to mid-Albian cosmopolitan genus Douvilleiceras is represented in the Haida Gwaii archipelago of western British Columbia by five species, D . mammillatum (Schlotheim), D . offarcinatum (White), D . scabrosum Casey, D . spiniferum (Whiteaves), and D . aff. spiniferum (Whiteaves). Specimens of one of these taxa, D . spiniferum , are particularly abundant on Haida Gwaii and the species is discussed with respect to its morphological variability and ontogenetic development. The important morphological features for taxonomic criteria of the genus Douvilleiceras are the mode of tuberculation, the pattern of ribbing, and the proportions of the shell in the middle growth stage.

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.
