Oligosphaeridium anthophorum
From dinoflaj2
"anthophorum" (Cookson and Eisenack, 1958, p.43, pl.11, figs.12-13; text-figs.16-18) Davey, 1969a, p.147. Holotype: Cookson and Eisenack, 1958, pl.11, fig.12; Fauconnier and Masure, 2004, pl.73, figs.5-6. NOW Stiphrosphaeridium. Originally Hystrichosphaeridium, subsequently Oligosphaeridium, thirdly Polystephanephorus, fourthly Hystrichosphaerina, fifthly (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 and Williams (1966b, p.77), since these authors did not fully reference the basionym. Age: Aptian-Albian.
