The Neogene biota of the Transantarctic Mountains
Bibliographic record
Abstract
Neogene fossil assemblages are described from three localities in the Transantarctic mountains. The plant fossils, include diatoms and algal spores, megaspores of Isoetes, pollen of angiosperms and gymnosperms, wood and leaves of Nothofagus, cushion growth forms of a vascular plant and a moss species, mats of exceptionally well- preserved moss species with delicate leaves attached to stems, and achenes and fruits of vascular plant species including Ranunculus. The invertebrate fossils include disarticulated chitinous parts of beetles and flies, cypridoidean ostracods and the shells of freshwater molluscs. The only vertebrate fossil is that of a fish. The fossil assemblages require considerably warmer temperatures than are available within the Transantarctic Mountains today; estimated to be at least two to three summer months annually with mean temperatures of 4-5°C. Early interpretations allowed for the extinction of this terrestrial biota to have occurred as late as the Pliocene but a Miocene age now seems more probable.
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.
