Palynomorph assemblages of terrestrial spores, acritarchs, chitinozoans, scolecodonts and plant fragments are relatively abundant and diverse in the lower 250 m of this formation. Taxa include the cryptosporegenera Cymbohilates, Acontotetras, Hispanaediscus, Laevolancis, and Tetrahedraletes, spore genera Ambitisporites, Aneurospora, Apiculiretusispora, Emphanisporites, Retusotriletes, Synorisporites, Vermiverruspora, and a new species Stellatispora fahraeusi. Acritarchs include the taxon Triangulina sanpetrensis and chitinozoa include Angochitina chlupaci. Palynomorphs indicate a Lochkovian age, corresponding with the Apiculiretusispora sp. E zone from Europe. In well preserved samples from this section, the fossil terrestrial palynomorph assemblages from these shallow marine deposits correspond closely in species diversity and concentration with values reported for modern shelf deposits located adjacent to low Arctic moss and sedge tundra. By inference, earliest Devonian terrestrial vegetation must have been relatively well developed on this ancient coastline. You do not currently have access to this article.

How this classification was reachedexpand
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.
