Abstract
A detailed LM and SEM examination of the Upper Cretaceous Timerdyakh Formation microflora from the Vilui Basin yielded 13 Aquilapollenites, two Manicorpus, and three Azonia species. Comparisons with existing taxa from the Russian Federation and North America are impeded by the fact that many previously described forms were investigated using LM only, while SEM was very rarely used. Consequently, some of the pollen types reported in this study could not be ascribed to any previously documented taxa and have been described as nine new species. Further one previously described variety has been renamed. Except for two Azonia species and four Aquilapollenites species that also occur in Alaska, Canada and the Rocky Mountains in USA, the remaining taxa described here are restricted to the Late Cretaceous Khatanga‐Lena‐Subprovince. The several species unique to the Vilui Basin might indicate separate evolutionary paths for the genera Aquilapollenites and Manicorpus in North America and both northern and southern Asia during the Upper Maastrichtian.

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 it
