Bibliographic record
Abstract
FILAMUSSIUM, GEN. NOV. (FIG. 7A–C) Type species: Pecten schafhäutli Winkler, 1859 (= Pecten velatus Schafhäutl, 1852; non Pecten velatus Goldfuss, 1833), Upper Triassic, Kothalpe am Breitenstein, Germany. Spelling automatically emended to Pecten schafhaeutli. Diagnosis: Propeamussiidae with right valve less convex than left or nearly flat, exterior of right valve smooth, that of left valve with intercalated radial costae of more than one order and finer, closely spaced commarginal lirae. Outer calcitic columnar prismatic layer of right valve consisting of small, polygonal prisms randomly arranged, not commarginally ordered or alternating in size, directly overlying an inner crossed-lamellar aragonitic layer in central region of disk; outer layer of left valve nonprismatic calcite, inner layer crossed-lamellar aragonite. Internal ribs present on both valves, widely and regularly spaced with distal termini well separated from ventral margin of disk; filosus structure present on inner surface of outer calcitic layer of left valve. Dentition of right valve with well-developed resilial teeth, fitting into well-developed resilial sockets on left valve. Comparison: Filamussium differs from members of the Entolioididae in having internal ribs. The new genus differs from other genera of Propeamussiidae in having a filosus structure on its left valve and in having internal ribs that were probably originally aragonitic rather than calcitic. Included species: In addition to the type species, the new genus includes Pecten (Variamussium) klushaensis Lees, 1934 and P. (V.) yukonensis Lees, 1934 both from the Upper Triassic (upper Norian Suessi Zone; Tozer, 1967: 80) of the Laberge area, Yukon. Occurrence: See preceding discussion of clade 4 – Propeamussiidae.

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.
