Rhombodinium rotundatum
Rhombodinium ?rotundatum Balteş, 1969, p.35, pl.5, fig.10 ex Lentin and Williams, 1973, p.121.
Originally Wetzeliella (name not validly published), subsequently (and now) Rhombodinium. Questionable assignment: Williams et al. (2015, p.311).
Taxonomic junior synonym (at specific rank): Rhombodinium draco forma freienwaldense (as Rhombodinium freienwaldense), by implication in Costa and Downie (1979, p.44), who believed Rhombodinium freienwaldense to be the senior name — however, Grabowska in Malinowskiej and Piwockiego (1996, p.343) retained Rhombodinium freienwaldense. This name was not validly published in Balteş (1969) since that author considered it a provisional designation.
Holotype: Balteş, 1969, pl.5, fig.10.
Age: Oligocene.
Original description (Baltes, 1969) Not yet translated from French
Descroption: Cyste à aspect rhomboïdal, longueur totale 140-160 microns, largeur 120-126 microns. Cornes apicale et notamment celles latérales considérablement arrondies. corne antapicale moulant toutefois deux proémineces légères. Pas de processus. Membrane extérieure lisse or finement granulée. Endophragme à contour ovoïdal occupant presque entièrement la cavité intérieure. Âge et localité: Marnes et sables oligocènes de la Dépression précarpathique, zone de Rm. Vilcea (Muiereasca).
