From Fensome et al., 2019:
Apteodinium verrucosum Oleinik, 1976, p.85, pl.1, figs.1–3. Holotype: Oleinik, 1976, pl.1, fig.1. Originally (and now)
Apteodinium, subsequently Apectodinium. This name was erroneously listed in Apectodinium (Costa and Downie,
1976) Lentin and Williams, 1977b in Lentin and Williams (1981, p.14); in the same publication, Lentin and
Williams (1981, p.17) correctly listed it as a species of Apteodinium. Age: Late Eocene.
