Pragian (Lower Devonian) stromatoporoids and rugose corals from Zújar (Sierra \nMorena, southern Spain)
Bibliographic record
Abstract
The locality Zújar at the boundary between the Badajoz and Córdoba provinces belongs to the Obejo-Valsequillo-Puebla \nde la Reina Domain. Within the fossiliferous reefal carbonates of Pragian age cropping out in Zújar, 10 stromatoporoid species and 7 \nrugose coral species are identified. The new rugose coral species Martinophyllum miriamae n. sp. is described. Hexagonaria soraufi \nRodríguez García, 1978 is a subspecies of Martinophyllum ornatum Jell & Pedder, 1969. The Pragian fauna of Zújar is a typical fauna of \nthe Old World Realm with remarkably close relationships to Arctic Canada and Australia. Most species have been recorded for the first \ntime from Spain. No significant relationships to the Eastern Americas Realm are visible. Remarkable is, that none of the stromatoporoid \nspecies of Zújar is known from the famous Pragian reef complex of Koněprusy in Bohemia, meanwhile the rugose coral fauna (e. g. \nJoachimastraea barrandei Galle, Hladil & May, 1999) shows some relations. Some of the species found are ancestors of important \nconstructors of the Middle Devonian reef complexes, demonstrating that the roots of the Givetian-Frasnian reef complexes reach down \nto the Pragian.

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.
