From dinoflaj3
"striolatum" (Deflandre, 1937b, p.72–73, pl.15 [al. pl.12], figs.1–2) Davey, 1969a, p.164. Holotype: Deflandre, 1937b, pl.15 (al. pl.12), fig.1. NOW Coronifera. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Exochosphaeridium, fourthly (and now) Coronifera. This combination was not validly published in Davey et al. (1966, p.166), since these authors did not fully reference the basionym. Age: Late Cretaceous.
