Taanella yukonensis n. gen. n. sp., a uniquely perforate agglutinated foraminifer from the upper triassic of Panthalassa (Lime Peak, Yukon, Canada)
Bibliographic record
Abstract
This paper describes the new calc-cemented, agglutinated Panthalassan species Taanella yukonensis n. gen. n. sp. from the upper Norian of Lime Peak, Yukon, Canada. The species, morphologically close to a Triassic “trochamminid”, possesses unusually coarse wall perforations. This attribute is unknown from coeval agglutinated forms, which typically display imperforate or poorly perforate walls (i.e., loose agglutinated tests with gaps between particles). In the Late Triassic, remarkably large pores started to develop in a variety of foraminifers, including porcelaneous forms. This evolutionary tendency might indicate a heightened need to promote gas-exchange with the exterior. In T. yukonensis, this evolution is complemented with the development of externally globular chambers, separated by deep sutural slits, maximizing the surface ratio to the exterior.
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.
