Alterbidinium pseudocirculum
Alterbidinium pseudocirculum, Vasilyeva in Andreeva-Grigorovich et al., 2011, p. 45–46, pl.11, figs.20–24; text-fig.18f ex Williams and Fensome, 2016, p.139.
This name was not validly published by Vasilyeva in Andreeva-Grigorovich et al. (2011, p.45–46) since the holotype citation (pl.11, figs.20–24 and text-fig.18f) includes more than one specimen. The holotype was clearly designated in Williams and Fensome (2016), thus validating the name Alterbidinium pseudocirculum. In the caption to text-fig. 18, the species is referred to as Alterbidinium pseudocingulum.
Holotype: Andreeva-Grigorovich et al., 2011, pl.11, figs.23–24; text-fig. 18f, designated by Williams and Fensome (2016, p.139).
Age: Danian–Selandian.
