Marine calcareous algae from the Devonian-Carboniferous transition beds
Bibliographic record
Abstract
La microflore alguaire de la fin du Famennien et du debut du Carbonifere est cosmopolite, non diversifiee et entierement non-caracteristique. Elle est composee de taxa paleozoiques de longue duree et ne montre aucune extinction ou premiere apparition de quelque importance.Les Spongiostromides (Malacostroma, Spongiostroma) sont rares. Parmi les Porostromides, Girvanella est ubiquiste tandis que Sphaerocodium disparait progressivement a la base du Carbonifere. Des codiacees nodulaires, a longue duree, (Bevocastria, Ortonella, Garwoodia, Pseudohedstroemia, Mitcheldeania) forment des oncolites complexes. Parmi les Codiacees massives, Poncetellina s'etend jusqu'a la base du Tournaisien. Les Udoteacees et les phylloides sont inconnus. L'extinction de la flore caracteristique devonienne se produit au Frasnien superieur et il y a un vide apparent dans l'evolution des Udoteacees jusqu'au renouveau tardi-tournaisien de la flore a Orthriosiphon. Les Dasycladacees sont toutes simples et representees par des vermiporellides, dasyporellides, issinellides et coelosporellides. Quelques-unes des flores les plus prolifiques sont composees de palaeoberesellides (Palaeoberesella, Pseudokamaena, Kamaena, Kamaenella et Exvotarisella). Les Solenoporides (Solenopora, Parachaetetes, Pseudosolenopora) sont generalement rares. Parmi les incertae sedis on remarque d'occasionnel Renalcis, Proninella, Wetheredella, Paleomicroco-dium, Kulikaella et Evlania ? Sycidium et Trochiliscus sont melanges a d'abondants umbellinides tels que Umbellina, Protoumbella, Ellenia, Biumbella et Quasiumbella.

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.
