NEW DATA ON ALBIAN BIOSTRATIGRAPHY OF THE NORTHERN REGION OF WEST SIBERIA (RELYING ON THE STUDY OF FORAMINIFERA)
Bibliographic record
Abstract
New data on foraminifera from the well section of the western slope of the Yamal Peninsula in West Siberia give an opportunity to clarify the biostratigraphy of the Khanty-Mansi horizon of this region. Two Albian substages have been identified at the Bovanenkovskaya area according to foraminifera assemblages: Ammobaculites fragmentarius, Gaudryinopsis filiformis (middle substage), Ammotium braunsteini, Verneuilinoides borealis assanoviensis (upper substage). Albian assemblages from well sections of the Yuzhno-Russkaya area are given as typical ones for comparison, they are also confined to the northern region of the West Siberian Province. Many of the discovered taxa are common species, subspecies or vicariants (substitutes) with those of the Trans-Urals and have similarities with the Albian taxa of Canadian province (Northern Alaska, Canada).
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.

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.
