Abstract

fetched live from OpenAlex

Abstract Complexes of the Costopyxis antiqua diatom zone and the Cornua trifurcata silicoflagellate zone dated presumably to the middle Campanian have first been established in the diatomite layer at the re-examination of the outcrop of marine Upper Cretaceous deposits on the Severnaya Sos’va River in the area of the Ust’-Manya settlement. Associations with at least 40 diatom species and 10 silicoflagellate species are typical of an epicontinental basin with seasonal contrast. Analogues from sections of the eastern slope of the Urals, Northern territories of Canada, and the southeastern part of the East European Platform are known, which indicates stable interbasin connections of the Panboreal realm in the Campanian.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
