Monographic study of the Late Cretaceous representatives of the bolivinoidid benthic foraminifera
Bibliographic record
Abstract
A high resolution taxonomy and classification framework is developed for the representatives of the calcareous benthic foraminiferal family Bolivinoididae; this family consists of 24 species assigned to three genera. This new classification includes data pertaining of the test ultrastructure, ornamentation and porosity, which are obtained with the aid of careful and extensive study of the specimens under the scanning electron microscope. Two new taxa are described: Bolivinoides antiquum – n. sp. and Swiecickina – n. gen. A biostratigraphical framework consisting of eleven biozones based on bioevents given by species of the genera Bolivinoides and Swiecickina is developed for the middle Santonian-Maastrichtian stratigraphical interval; its resolution is more than double when compared to those of the previously developed biostratigraphical frameworks based on the representatives of this group.
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.
