Dracodinium rhomboideum subsp. ovale

"subsp. ovale" Andreeva-Grigorovich and Savitskaya, 1993, p.44–45, pl.1, figs.5,7–8.  Holotype: Andreeva-Grigorovich and Savitskaya, 1993, pl.1, fig.5; Andreeva-Grigorovich et al., 2011, pl.20, fig.2.  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.  Age: early Eocene.
