Cribroperidinium edwardsii
?edwardsii (Cookson and Eisenack, 1958, p.32, pl.3, figs.5–6; text-fig.7) Davey, 1969a, p.128. Holotype: Cookson and Eisenack, 1958, pl.3, fig.6; text-fig.7; Jan du Chêne et al., 1986a, pl.32, fig.4; pl.33, fig.3. Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Cribroperidinium, fourthly (and now) Cribroperidinium?. Questionable assignment: Helenes (1984, p.125) as a problematic species. Taxonomic junior synonyms: Gonyaulax (now Cribroperidinium) apione, according to Burger (1980a, p.82) — however, Jan du Chêne et al. (1986a, p.76) retained Cribroperidinium apione; Gonyaulax (as Cribroperidinium) orthoceras, according to Davey and Verdier (1971, p.17) — however, Below (1981a, p.39–40) and Lentin and Williams (1985, p.79) retained Cribroperidinium orthoceras. Age: Albian–early Turonian.
