Achomosphaera neptuni
From dinoflaj2
neptuni (Eisenack, 1958a, p.399, pl.26, figs.7-8; text-fig.8) Davey and Williams, 1966a, p.51-52. Emendations: Duxbury, 1983, p.55, as Spiniferites neptuni; Sarjeant, 1985a, p.89-90,92, as Florentinia? neptuni. Holotype: Eisenack, 1958a, pl.26. fig.7. Originally Baltisphaeridium (Appendix A), subsequently (and now) Achomosphaera, thirdly Achomosphaera?, fourthly Spiniferites, fifthly Florentinia?. Questionable assignment: Stover and Evitt (1978, p.139) - however, Lister and Batten (1988b, p.31-32) retained this species in Achomosphaera without question. Since the epithet is based on a given name, it ends in "i" rather than "ii" (I.C.B.N. Recommendation 60C.2). Age: Early Cretaceous.
