Barremian palynofloras from the Ashikajima and Kimigahama formations (Choshi Group, Outer Zone of south-west Japan)
Bibliographic record
Abstract
Incertae sedis sp. 2 (Fig. 13C) Incertae sedis sp. G, Legrand, Palynologie des dépôts Jurassique supérieur et Crétacé inférieur du Japon, et provinces paléofloristiques du sud-est asiatique: 195, pl. XXI, fig. 7 (2009). OCCURRENCE. — Ashikajima Fm. DESCRIPTION Pollen grain. Amb oval in polar view. An eight shape wide median sulcus with rounded ends, runs through the grain. In the middle part of the grain, the edges of the sulcus strongly widen (until 10-12 µm), and can fold one over the other. This thickening can widen progressively or quite abruptly. The exine is psilate (about 1.5 µm thick). Length × width = 40-50 × 30- 35 µm; longitudinal thickenings (length × width) = 25 × 10-12 µm. REMARKS These grains have similarities with Cycadopites, but the folded lips that can be observed here on some grains are much more developped. The genus Entylissa Naumova ex Ischenko, shows developped lips, but slenderer and more ornamented than in Incertae sedis sp. 2. McGregor (1965) figured a pollen grain similar to our species: cf. Ginkgocycadophytus caperatus (Luber, 1941) Samoilovich, 1953 (pl. 5, fig. 25), from the Upper Jurassic of Canada. Monosulcites scaber Kimyai, 1966 reported from the Cretaceous of New Jersey, USA (Kimyai 1966), also shows great similarities to our species. BOTANICAL AFFINITIES Gymnosperms.

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.
