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).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
