Baltisphaeridium geometricum

"Baltisphaeridium geometricum" (Pastiels, 1948, p.41, pl.4, figs.1-11 ex Downie and Sarjeant, 1965, p.90) Fensome et al., 1990, p.617.

TYPE: Holotype: Pastiels, 1948, pl.4, fig.4.

HISTORY: NOW: Apectodinium. Originally Hystrichosphaeridium geometricum (name illegitimate), subsequently Baltisphaeridium geometricum, thirdly Apectodinium pastielsii (name illegitimate), fourthly (and now) Apectodinium pastielsii.

SYNONYM(S): Nomenclatural junior synonym: Apectodinium pastielsii, which has the same type. Taxonomic junior synonym (at specific rank): Wetzeliella homomorpha var. quinquelata (as Wetzeliella quinquelata; now Apectodinium quinquelatum), by implication in Harland (1979c, p.67), who believed the latter to be the senior name - however, Lentin and Williams (1989, p.18) retained Apectodinium quinquelatum.

AGE: Ypresian.
