Cordosphaeridium erectum

"?erectum" (Manum and Cookson, 1964, p.14, pl.3, figs.5–6) Davey and Williams, 1969, p.6.  Holotype: Manum and Cookson, 1964, pl.3, fig.5.  NOW Kiokansium?.  Originally Hystrichosphaeridium, subsequently Baltisphaeridium (Appendix A), thirdly Cordosphaeridium?, fourthly Cleistosphaeridium?, fifthly (and now) Kiokansium?.  Questionable assignment: Davey and Williams (1969, p.6).  This combination, as a questionable assignment, was not validly published in Davey and Williams (1966b, p.91), since these authors did not fully reference the basionym.  Age: Albian–Turonian.
