Gonyaulacysta nuciformis
From dinoflaj2
"nuciformis" (Deflandre, 1939a, p.180, pl.8, figs.4-6 ex Sarjeant, 1962a, p.482-483) Sarjeant, 1968, p.227. Holotype: Deflandre, 1939a, pl.8, fig.6; Jan du Chêne et al., 1986a, pl.11, figs.1-3. NOW Cribroperidinium. Originally Palaeoperidinium (name not validly published), subsequently Gonyaulax (Appendix B), thirdly Gonyaulacysta, fourthly Apteodinium, fifthly Millioudodinium, sixthly (and now) Cribroperidinium. Taxonomic junior synonym: Palaeoperidinium nuciformoides, according to Sarjeant (1968, p.227). This combination, as a questionable assignment, was not validly published in Sarjeant (1966b, p.132), since that author did not fully reference the basionym. Age: Oxfordian.
Parent: Gonyaulacysta
