The palynostratigraphy of the Edmonton Group (Upper Cretaceous) of Alberta, Canada
Bibliographic record
Abstract
Palynological studies of the mainly terrestrial Edmonton Group in Alberta, Canada have been undertaken for the last 64 years. The Edmonton Group is of Late Cretaceous (Campanian–Maastrichtian) age and was deposited on the northwestern fringes of the regressing North American inland sea. Satish K. Srivastava initiated the detailed palynological study of the Edmonton Group, publishing many papers on the taxonomy and biostratigraphy of this unit. Subsequent palynological studies have produced significant additional information about the biostratigraphy of these strata. The accumulated data on lithostratigraphy, magnetostratigraphy and radiometric dating have allowed for a better understanding of the group. Satish K. Srivastava formalized many species from the Edmonton Group and a list of type specimens is provided together with new curation information. All of the microscope slides have been transferred to the collections of the Royal Tyrrell Museum. Neotypes and lectotypes are herein designated and illustrated for 21 missing original type specimens. Wodehouseia edmontonicola is emended and new combinations are proposed for Expressipollis catterallii, Siberiapollis major and Corrugatisporites verrucosus. The ranges of selected species provide an updated biostratigraphy for the Edmonton Group.

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.
