Cribroperidinium granuligerum
Cribroperidinium granuligerum (Klement, 1960, p.41-42, pl.5, figs.4-5) Stover and Evitt, 1978, p.150. Emendation: Sarjeant, 1984a, p.156, as Cryptarchaeodinium granuligerum.
Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly (and now) Cribroperidinium, fourthly Rhynchodiniopsis, fifthly Cryptarchaeodinium, sixthly Acanthaulax. Poulsen (1996, p.75) retained this species in Cribroperidinium.
Taxonomic senior synonym: Gonyaulax (as Cribroperidinium) granulata, according to Fisher and Riley (1980, p.321) - however, Sarjeant (1984a, p.156-158) retained Gonyaulax (as Cryptarchaeodinium) granuligera.
Holotype: Klement, 1960, pl.5, figs.4-5; Sarjeant, 1984a, pl.1, figs.3-4; text-fig.1; Jan du Chêne et al., 1986a, pl.27, figs.11-14.
Age: Middle Oxfordian-Early Kimmeridgian
Translation Courtinat, 1989: LPP
Remark: Courtinant, 1989, p.203
Fisher and Riley (1980) are of the opinion that C. granulatum, C. granuligerum and Rhynchodiniopsis angulosa are different morphologies of the same species. Sarjeant (1984), after study of the holotype and paratypes, maintained a separation of C. granulatum and C. granuligerum. R. angulosa has a differentparatabulation than the former two species. However, these two species, granulatum and granuligerum, have an identical entral and sulcal arrangement. They differ in the ornamentation and the more or less strong development of secondary septa parallel to the principal sutures. In the Jura, their occurrences are different; this suggests that these two species belong to the same offspring.

Cribroperidinium granuligerum (Klement, 1960), Stover and Evitt, 1978; Lentin and Williams, 1985, p.81.
Acanthaulax granuligera (Klement, 1960), Brenner, 1988; p. 35-36, pl. 2, figs. 1-3.
Remarks. Riley (1980), Lentin and Williams (1981) and Helenes (1984) regarded Cribroperidinium granuligerum as a taxonomic junior synonym of C. granulatum. Brenner (1988, p. 34-36) treated C. granuligerum as a separate species. This is followed here. For the differentiation of C. granuligerum and C. granulatum see remarks under the latter species.
Recorded occurrence. Denmark: Kimmeridgian.
