Phanerodinium sonciniae

"?sonciniae" Marheinecke, 1992, p.110–111, pl.25, figs.1–4.  Holotype: Marheinecke, 1992, pl.25, figs.1–2.  NOW Microdinium.  Originally Phanerodinium?, subsequently (and now) Microdinium.  Questionable assignment: Marheinecke (1992, p.110).  Taxonomic junior synonym: Microdinium perplexum (name not validly published), according to Slimani (2001a, p.193).  Contrary to the opinion of Lentin and Williams (1993, p.509), Williams et al. (1998, p.480) considered this name to be validly published.  Age: late early–late late Maastrichtian.
