Wetzeliella pachyderma
From dinoflaj3
"pachyderma" Caro, 1973, p.365, pl.3, figs.4–6. Holotype: Caro, 1973, pl.3, fig.4. Originally Wetzeliella, subsequently Dracodinium. Taxonomic senior synonym: Wetzeliella (now Dracodinium) eocaenica, by implication in Caro (1973, p.365), who considered the name Wetzeliella eocaenica to be not effectively published. Williams et al. (2015, p.304) also considered Dracodinium pachydermum to be a taxonomic junior synonym of Dracodinium eocaenicum. Age: early Eocene.
Parent: Wetzeliella
