Adpressed tree-fern trunks from the Early Pennsylvanian Joggins Formation of Nova Scotia
Bibliographic record
Abstract
Tree-fern trunks are among the rarest plant fossils in the Early Pennsylvanian Joggins Formation, with only three specimens recorded, all of which are assigned to Artisophyton. Based on trunk dimensions, these fossils are remains of small trees a few metres high. The facies context is known for only one specimen; this tree grew on a well drained, seasonally dry alluvial plain.
 
 Resumé
 
 Les troncs de fougère arborescente figurent parmi les fossiles végétaux les plus rares à l’intérieur de la Formation du Pennsylvanien précoce de Joggins : on y a seulement relevé trois spécimens, tous classés parmi les Artisophytons. Les dimensions des troncs signalent que ces fossiles constituent des vestiges de petits arbres de quelques mètres de hauteur. On ne connaît le contexte du faciès que dans le cas d’un spécimen : l’arbre en question a grandi dans une pleine alluviale sèche en certaines saisons et bien drainée.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
