Alterbidinium simplex
Alterbidinium simplex, Vasilyeva in Andreeva-Grigorovich et al., 2011, p.47–48, pl.12, figs.1–4; text-fig.18h ex Williams and Fensome, 2016, p.139.
This name was not validly published by Vasilyeva in Andreeva-Grigorovich et al. (2011, p.47–48) since the holotype citation (pl.12, figs.1–4 and text-fig.18h) includes more than one specimen. The holotype was clearly designated in Williams and Fensome (2016), thus validating the name Alterbidinium simplex.
Holotype: Andreeva-Grigorovich et al., 2011, pl.12, figs.1–2; text-fig. 18h, designated by Williams and Fensome (2016, p.139).
Age: Thanetian–Ypresian.
