Oligosphaeridium paradoxum
From dinoflaj2
"?paradoxum" (Brosius, 1963, p.41-42, pl.4, figs.1,6; text-fig.2, nos.1a-c) Davey and Williams, 1969, p.5. Holotype: Brosius, 1963, pl.4, fig.6; Fensome et al., 1995, fig.2 - p.1639. NOW Distatodinium. Originally Hystrichosphaeridium, subsequently Tanyosphaeridium, thirdly Oligosphaeridium?, fourthly (and now) Distatodinium, fifthly Bipolaribucina. Questionable assignment: Davey and Williams (1969, p.5). This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.77), since these authors did not fully reference the basionym. Age: Late Oligocene.
Parent: Oligosphaeridium
