opacum Brideaux, 1971, p.76-77, pl.21, figs.19-22; text-figs.7d-e. Holotype: Brideaux, 1971, pl.21, figs.21-22; text-figs.7d-e. Originally (and now) Microdinium, subsequently Phanerodinium. Lentin and Williams (1989, p.245) retained this species in Microdinium. Taxonomic junior synonym: Microdinium spinosum, according to Below (1987b, p.38). Below (1987b, p.39) considered Microdinium (as Phanerodinium) distinctum to be the questionable taxonomic senior synonym of this species. Age: Mid-Late Albian.
