Palaeoglenodinium cretaceum
From Fensome et al., 2019:
Palaeoglenodinium cretaceum Deflandre, 1935, p.227, pl.7, figs.2–3. Holotype: Deflandre, 1934, figs.2–3; Deflandre, 1935, pl.7, figs.2–3; Deflandre, 1936b, pl.3, figs.5–6. Sarjeant in Lentin and Williams (1989, p.272) recommended that this name be restricted to the holotype. This species was not validly published in Deflandre (1934, caption to fig.3 — p.967) since no description was provided. A full description of this species appeared in Deflandre (1936b, p.172). Age: ?Senonian.

Original description (Deflandre, 1935) Translation: PKB
Let us move on to the other genera of Dinoflagellates. I have already shown an organism that I consider very close to the Glenodinium: the Palaeoglenodinium cretaceum. I will give a figure of it here: while presenting a transverse furrow and a longitudinal furrow, like the Peridinium, it did not seem to me to show any trace of tabulation. This tabulation, which characterizes the Peridiniidae, does not appear, however, on all the specimens that I do not hesitate to classify in this family, often thanks to their most characteristic physiognomy.
