Cleistosphaeridium multifurcatum

"Cleistosphaeridium? multifurcatum" (Deflandre, 1937b, p.76, pl.16 [al. pl.13], figs.1-3) Davey et al., 1969, p.16.

TYPE: Holotype: Deflandre, 1937b, pl.16 (al. pl.13), figs.1-2; Fensome et al., 1991, figs.1-2 - p.691; fig.1 - p.693; Fensome et al., 1993a, fig.1 - p.1261; figs.1-2 - p.1265.

HISTORY: NOW: Heterosphaeridium. Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cleistosphaeridium, fourthly Cleistosphaeridium?, fifthly (and now) Heterosphaeridium. Questionable assignment: Stover and Evitt (1978, p.31).

COMMENTS: This combination was not validly published in Davey et al. (1966, p.170), since these authors did not fully reference the basionym.

AGE: Late Cretaceous.
