Cribroperidinium globatum
From dinoflaj3
globatum (Gitmez and Sarjeant, 1972, p.195,197, pl.3, figs.1–2; text-figs.5A–B) Helenes, 1984, p.124. Holotype: Gitmez and Sarjeant, 1972, pl.3, fig.1; text-fig.5A; Jan du Chêne et al., 1986a, pl.29, fig.3. Originally Gonyaulacysta, subsequently Millioudodinium, thirdly Rhynchodiniopsis, fourthly Cribroperidinium?, fifthly (and now) Cribroperidinium. Questionable assignment: Helenes (1984, p.124) as a problematic species — however, Poulsen (1996, p.72) included the species in Cribroperidinium without question. Taxonomic junior synonyms: Gonyaulacysta cauda and Gonyaulacysta systremmata, both according to Poulsen (1996, p.72). Age: middle-late Kimmeridgian.
