Gonyaulacysta longicornis
From dinoflaj2
"?longicornis" (Downie, 1957, p.420, pl.20, fig.8; text-figs.2a-b) Sarjeant, 1969, p.10. Holotype: Downie, 1957, pl.20, fig.8; text-figs.2a-b; Jan du Chêne et al., 1986a, pl.30, fig.1. NOW Cribroperidinium?. Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta, thirdly Gonyaulacysta?, fourthly Millioudodinium, fifthly (and now) Cribroperidinium?. Questionable assignment: Stover and Evitt (1978, p.158). This combination, as a questionable assignment, was not validly published in Sarjeant (1966b, p.131), since that author did not fully reference the basionym. Age: Late Kimmeridgian.
Parent: Gonyaulacysta
