Abstract

fetched live from OpenAlex

The late Westphalian – early Stephanian macrotloras of the Dobrudzha Coalfield show many similarities with the contemporaneous lowland assemblages from southern Britain and the Canadian Maritimes, but there are also present some taxa normall y associated with more upland basins such as Saar-Lorraine and Central Bohemia. This is in agreement with the Dobrudzha Coalfield occupying a marginal position on the Variscan Foreland, perhaps at higher altitudes than the more western coalfields. It has been possible to identify the main biozonal boundaries that were originally established in western Europe and eastern North America. The base of the Laveineopteris rarinervis Subzone occurs at coal m5 in the Makedonka Formation. The base of the Linopteris bunburii Zone (indicating the base of the Westphalian D Stage) is at coal n3 in the Krupen Formation. The Lobatopteris micromiltoni Subzone seems to be absent due to a nonsequence, but the Dicksonites plueckenetii Subzone is in the Gurkovo Formation. Evidence of the Odontopteris cantabrica Zone (indicating the Westphalian – Stephanian boundary) occurs at coal p7 in the upper Gurkovo Formation.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
