Cerodinium prutense
From Fensome et al., 2019:
Cerodinium prutense (Grigorovich, 1971, p.92,94, pl.2, fig.2) Lentin and Williams, 1987, p.115. Holotype: Grigorovich, 1971, pl.2, fig.2. Originally Ceratiopsis (generic name illegitimate), subsequently Deflandrea?, thirdly (and now) Cerodinium. Age: Paleocene.
---------------------------------------------------------------------------------------------------
Original description: [Grigorovich, 1971] (translated from Russian):
Ceratiopsis prutensis, Grigorovitch, sp. nov. (Table 11, Fig. 2)
Holotype. IHGG I, Academy of Sciences of the Ukrainian SSR, specimen 446-11; Paleocene (Danian), Upper Stryi Formation, Prut River.
Diagnosis: The theca is strongly elongated with the internal body protruding laterally. The epitheca is triangular and gradually becomes a long apical horn. Hypotheca with two wide antapical processes at the oonovany, of which one is often reduced.
The internal body is spherical. The theca is smooth and transparent. Dimensions of the tolotila [?] in microns: Length 120, width 69.
Location and material. Outcrop on the Prut River, Yaremcha village; Upper Stroyskaya Formation (Danian); preparation 476, 6 specimens. Outcrop along the Opor River; lower part of the Manyavskaya Formation (Lower Eocene); preparation 518, 10 specimens.
