Stiphrosphaeridium dictyophorum
From dinoflaj2
*dictyophorum (Cookson and Eisenack, 1958, p.44, pl.11, fig.14) Lentin and Williams, 1985, p.340. Holotype: Cookson and Eisenack, 1958, pl.11, fig.14; Fensome et al., 1993a, fig.1 - p.1125. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Oligosphaeridium, fourthly (and now) Stiphrosphaeridium. This combination was not validly published in Davey (1982b, p.16,35) since that author did not give a reference for Cookson and Eisenack (1958). Age: Late Jurassic.
Parent: Stiphrosphaeridium
