Abstract

fetched live from OpenAlex

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 distilled prediction

Teacher imitation

Not 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.
