Leptodinium porosum
From dinoflaj2
porosum (Lejeune-Carpentier, 1946, p.B193,B196; text-fig.6) Sarjeant, 1969, p.13. Emendation: Lejeune-Carpentier and Sarjeant, 1981, p.7-8, as Leptodinium porosum. Holotype: Lejeune-Carpentier, 1946, text-fig.6; Lejeune-Carpentier and Sarjeant, 1981, pl.3, figs.1-2; text-fig.4. Originally Gonyaulax (Appendix B), subsequently Gonyaulacysta (combination not validly published), thirdly (and now) Leptodinium, fourthly Leptodinium?. Questionable assignment: Stover and Evitt (1978, p.171) as a problematic species - however, Lejeune-Carpentier and Sarjeant (1981, p.7) included the species in Leptodinium without question. Jan du Chêne et al. (1986a, p.211) recommended that this name be restricted to the holotype. Age: Senonian.
Parent: Leptodinium
