First occurrence of the Ichnogenus Selenichnites from the Middle Jurassic Strata of the Skoura Syncline (Middle Atlas, Morocco); Palaeoecological and palaeoenvironmental context
Bibliographic record
Abstract
Des traces d’invertébrés, attribuées à l’ichnogenre Selenichnites , ont été découvertes dans les couches d’âge Bajocien supérieur–Bathonien inférieur (formation d’Ich Timellaline/Bou Akrabène) du synclinal de Skoura, dans le Moyen Atlas marocain. Conservées sur une dalle gréso-calcaire subhorizontale, ces traces montrent des formes en croissant ou fer à cheval avec, dans le spécimen le mieux conservé, une empreinte arrière selon l’axe médian (trace du telson caudal). Elles sont interprétées comme des traces d’enfouissement (fodinichnia) de Xiphosures (= Limules) cherchant leur nourriture sur le fond sablo-carbonaté ou sous un voile de vase le recouvrant. Les caractères sédimentologiques indiquent des dépôts subtidaux dans une zone peu profonde relativement abritée. Ces paléoenvironnements littoraux précèdent la régression bathonienne du domaine atlasique. Cette découverte permet d’établir la présence de Xiphosuridés sur les rivages sud de la Téthys dès le Jurassique moyen.

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.
