bicuneatum (Deflandre, 1939a, p.180, pl.8, fig.7 ex Sarjeant, 1967b, p.248) Courtinat, 1989, p.220. Holotype: Deflandre, 1939a, pl.8, fig.7. Originally Palaeoperidinium, subsequently Scriniodinium, thirdly Glossodinium, fourthly Dinopterygium, fifthly (and now) Cornudinium. The name Palaeoperidinium bicuneatum was not validly published in Deflandre (1939a) since the generic name Palaeoperidinium was not validly published until 1967. Williams et al. (1998, p.141) accepted Sarjeant's (1967b) indirect reference to Deflandre (1939a), in which the name Palaeoperidinium bicuneatum was first proposed, as indication of a type (I.C.N. Article 40.3). Age: Oxfordian.
Parent: Cornudinium
