Prolixosphaeridium mixtispinosum
From dinoflaj3
mixtispinosum (Klement, 1960, p.58–59, pl.6, figs.17–19) Davey et al., 1969, p.17. Holotype: Klement, 1960, pl.6, figs.17–18; Sarjeant, 1984a, pl.4, fig.4; Fauconnier and Masure, 2004, pl.66, figs.2–3. Originally Baltisphaeridium (Appendix A), subsequently (and now) Prolixosphaeridium. Taxonomic junior synonym: Prolixosphaeridium basifurcatum, according to Courtinat (1989, p.182) — however, Fauconnier and Monteil in Fauconnier and Masure (2004, p.461) retained Prolixosphaeridium basifurcatum. This combination was not validly published in Davey et al. (1966, p.173), since these authors did not fully reference the basionym. Age: early Kimmeridgian.
