Ceratiopsis baltica, (Vozzhennikova, 1967), Lentin and Williams, 1977
Combination illegitimate since the generic name Ceratiopsis is illegitimate.
Now Cerodinium. Originally (and now) Cerodinium, subsequently Detlandrea, thirdly Ceratiopsis (combination illegitimate).
Stover and Evitt, 1978, retained this species in Deflandrea Eisenack, 1938. Lentin and Williams, 1981, retained it in Cerodinium Vozzhennikova, 1963.
Holotype: Vozzhennikova, 1967, pl.117, figs.2a-b; Lentin and Vozzhennikova, 1990, pl.2, figs.4-6, text-fig.14
Locus typicus: Baltic (Kaliningrad region), Russia
Stratum typicum: Eocene

Epitheca conical with a narrow, curved apical horn at the tip. Hypotheca smaller than epitheca, trapeziform with concave sides and straight or curved antapical horns which are widely separated. Transverse furrow shallow, annulate, equatorial and somewhat projecting on the lateral walls of the theca. Longitudinal furrow situated on the hypotheca. Margins of furrows with short outgrowths. Internal body oval bright yellow, its surface granular. Theca yellow colored, smooth or finely dotted. Pylome trapeziform.
