"granulata" Klement, 1960, p.39-41, pl.4, figs.10-13; text-figs.18-20.  Emendation: Sarjeant, 1984a, p.161-162, as Meristaulax granulata.  Holotype: Klement, 1960, pl.4, figs.10-11; text-figs.18-20; Fensome et al., 1995, figs.1-2 - p.1525; disintegrated according to Sarjeant (1984a, p.162).  Lectotype (designated by Sarjeant, 1984a, p.162): Sarjeant, 1984a, pl.3, figs.3-4; text-fig.3; Jan du Chêne et al., 1986a, pl.27, figs.7-10; Brenner, 1988, pl.3, figs.2a-b; Fensome et al., 1995, figs.5-6 - p.1525 - however, Brenner (1988, p.35) argued that this specimen is not conspecific with the holotype.  Lectotype (designated by Brenner, 1988, p.35): Brenner, 1988, pl.1, figs.3a-c; Fensome et al., 1995, figs.7-9 - p.1525.  NOW Cribroperidinium.  Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly (and now) Cribroperidinium, fourthly Rhynchodiniopsis, fifthly Meristaulax Sarjeant, sixthly Acanthaulax. Poulsen (1996, p.73) retained this species in Cribroperidinium.  Taxonomic junior synonyms: Gonyaulax (as Cribroperidinium) venusta, according to Schrank (2005, p.56); Gonyaulax (now Cribroperidinium) granuligera, according to Fisher and Riley (1980, p.321) - however, Sarjeant (1984a, p.156-158) retained Gonyaulax (as Cryptarchaeodinium) granuligera; Gonyaulacysta (as Acanthaulax?, now Cribroperidinium) angulosa, according to Fisher and Riley (1980, p.321) - however, Sarjeant and Gocht in Sarjeant (1984a, p.160) retained Gonyaulacysta (as Meristaulax) angulosa.  For further discussion, see Cribroperidinium granulatum.  Age: Mid Oxfordian-Early Kimmeridgian.
