Stiphrosphaeridium anthophorum
From dinoflaj2
anthophorum (Cookson and Eisenack, 1958, p.43, pl.11, figs.12-13; text-figs.16-18) Lentin and Williams, 1985, p.340. Holotype: Cookson and Eisenack, 1958, pl.11, fig.12; Fauconnier and Masure, 2004, pl.73, figs.5-6. Originally Hystrichosphaeridium, subsequently Oligosphaeridium, thirdly Polystephanephorus, fourthly (and now) Stiphrosphaeridium. Taxonomic junior synonym: Hystrichosphaerina schindewolfii, according to Davey (1979c, p.65) - however, Lentin and Williams (1981, p.150) retained Hystrichosphaerina schindewolfii. This combination was not validly published in Davey (1982b, p.18,35) since that author did not give a reference for Cookson and Eisenack (1958). Age: Aptian-Albian.
