Ceratiopsis markovae
Ceratiopsis markovae, Vozzhennikova, 1967, p.159, pl.119, figs.5,7; pl.120, figs.1–4.
NOW Cerodinium. Originally Ceratiopsis (generic name illegitimate), subsequently Deflandrea, thirdly (and now) Cerodinium. Following I.C.N. Article 55.1, the species name Ceratiopsis markovae is validly published even though the generic name Ceratiopsis is illegitimate.
Holotype: Vozzhennikova, 1967, pl.120, fig.2; Lentin and Vozzhennikova, 1990, pl.3, figs.7–8; text-fig.16.
Age: Paleocene.

Original description: [Vozzhennikova, 1967, p.159]:
Description:
Epitheca larger than hypotheca with outline conical or more rarely funnel-shaped. The apical horn is short, bluntly rounded or pointed, slightly tapering or not tapering. Hypotheca smaller than epitheca with short triangular apical horns. Transverse furrow shallow, annulate, displaced towards the hinder end of the theca. Longitudinal furrow extends to the antapex. Internal body large, ovoid, its surface finely granular and colored bright yellow or pale brown. Theca closely appressed to the internal body, thin-walled, transparent, delicate. Surface of theca smooth or finely tuberculate. Pylome large, round- trapeziform and situated near the transverse furrow or, more rarely, nearer to the apex.
