Bibliographic record
Abstract
Fig. 2. Enlarged scales of the sarcopterygian Eusthenopteron foordi Whiteaves, 1881 (MNHM 06−342) from the Late Devonian, Escumenac Bay, Quebec, Canada. A. SEM. Ornamentation of the outer surface of an enlarged dermal scale. B. SEM. Detail of the ornamentation of the outer surface of an enlarged dermal scale. The holes (arrows) correspond with the aperture of vascular canals. C. Vertical section of an enlarged dermal scale in transmitted natural light (C1) and in polarised light (C2). The outer layer composed of superficial parallel−fibered bone covers a discontinuous layer of woven−fibered bone containing primary and secondary osteons. Sharpey's fibres (white arrows) cross the superficial parallel−fibered bone. The basal plate is characterised by the presence of lamellar bone. D. Transmitted natural light (detail of C). The outer layer of an enlarged dermal scale. The secondary osteon is separated by a resorption line (black arrowhead) from the surrounding primary bone where Sharpey's fibres (white arrow) are abundant. Insert: the primary osteon, showing the absence of a resorption line (black arrowheads). Abbreviations: lb, lamellar bone; pf, parallel−fibered bone; post, primary osteon; sost, secondary osteon; vc, vascular canal; wf, woven−fibered bone.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
