Abstract
EmsianEifelian lingulate brachiopods from the Daleje-Tøebotov Formation (Tøebotov and Suchomasty limestones) and the Choteè Formation (Choteè and Acanthopyge limestones) from the Prague Basin; the Czech Republic MICHAL MERGL & STANISLAVA VODRÁKOVÁ Taxonomic composition and stratigraphic distribution of lingulate brachiopod taxa around the Emsian/Eifelian boundary of the Prague Basin were examined.Twelve species have been determined and the presence of others is suggested.The prevalence of micromorphic biernatids, Havlicekion and Opsiconidion, in all the studied samples is significant.A mode of life for biernatids, especially from the genus Opsiconidion, is discussed.A new Devonian occurrence of the siphonotretid Orbaspina is recorded.Lingulate brachiopods do not display any significant change around the Emsian/Eifelian boundary or at the Basal Choteč Event (Middle Devonian, Eifelian, costatus Zone) and thus confirm the general uniformity of lingulate faunas in the Lower and early Middle Devonian.•

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.
