Uncommon branching pattern within conifers: <i>Frenelopsis turolensis</i>, a Spanish Early Cretaceous Cheirolepidiaceae
Bibliographic record
Abstract
The fossil plant Frenelopsis turolensis Gomez from the Lower to Middle Albian of the Escucha Formation (Iberian Ranges, Spain) displays a combination of leaf and branch arrangements unknown in extant conifers. Detailed architectural analyses allow for elucidation of the branching pattern of this species. Branching occurs above a leaf of the whorl but at some distance from the node, within the internodal region. This event may be the result of adnation or hypomerithallus formation. We point out a new type of branching pattern for Frenelopsis based on F. turolensis, with no discontinuity in the leaf sequence. This unusual ontogeny of the branches asserts that branching is more diverse in the fossil cheirolepidiaceous genus Frenelopsis than previously supposed.Key words: branching pattern, ontogeny, Cheirolepidiaceae, Frenelopsis, Cretaceous, Spain.

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; a candidate call from one teacher head, not a consensus.
