Dracodinium subsp. ovale Andreeva-Grigorovich and Savitskaya, 1993, p.44-45, pl.1, figs.5,7-8.

NOW Petalodinium rhomboideum? subsp. ovale. Originally Dracodinium rhomboideum? subsp. ovale, subsequently (and now) Petalodinium rhomboideum? subsp. ovale.
Andreeva-Grigorovich and Savitskaya (1993) cited this taxon as "Dracodinium rhomboideum subsp. ovale (Grigorovich, 1971) emend. Andreeva-Grigorovich and Savitskaya". However, Rhombodinium rhomboideum forma ovale was not validly published in Grigorovich (1971), since that author did not provide a description.

Holotype: Andreeva-Grigorovich and Savitskaya, 1993, pl.1, fig.5.
Age: Early Eocene.
