Material.> 30 specimens. Remarks. Goel (1977), Matsuda (1984), Koike (1988) and Maekawa et al. (2018) documented a large intraspecific variation of the platform morphology and its oral ornamentation. It follows that Platyvillosus paracostatus Wang and Cao (1981) likely corresponds to a variant of Eu. costatus (Form A in Koike 1988). Maekawa et al., (2018, figs. 25.1d) documented also specimens covered with microgranules. Occurrence. Tis species has been reported worldwide from the early Smithian Flemingites zone. Japan: Tahogawa member within the Novispathodus ex gr. waageni Zone (Koike, 1988; Maekawa et al., 2018), Europe: South Tyrol, Slovenia, Croatia and Bosnia and Herzegovina (Aljinović et al., 2006; Chen et al., 2016; Kolar-Jurkovšek et al., 2021; Staesche, 1964), India: Spiti and Kashmir (Goel, 1977; Matsuda, 1984; Orchard, 2010; Orchard & Krystyn, 2007), Russia; South Primorye (Shigeta, 2009), Canada: British Columbia (Beyer & Orchard, 1991), South China and North-eastern Vietnam (Chen et al., 2015; Shigeta et al., 2014).

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.
