Peridinium pyrophorum Appendix B

"pyrophorum" Ehrenberg, 1837b, pl.1, figs.1,4 ex Wetzel, 1933a, p.164–165.  Emendations: Sarjeant, 1967b, p.246–247; Gocht and Netzel, 1976, p.403–405, both as Palaeoperidinium pyrophorum.  Holotype: Ehrenberg, 1837b, pl.1, fig.4; Lejeune-Carpentier, 1938b, figs.1–4.  NOW Palaeoperidinium.  Originally Peridinium, subsequently (and now) Palaeoperidinium.  Taxonomic junior synonyms: Peridinium (now Palaeoperidinium) basilium and Palaeoperidinium deflandrei, both according to Stover and Evitt (1978, p.218); Pentagonum marginatum, Pentagonum sibiricum, and Peridinium conicum var. larjakiense (as Palaeoperidinium larjakiense), all according to Lentin and Vozzhennikova (1990, p.61).  This name was not validly published in Ehrenberg (1837b) and Ehrenberg (1854, caption to pl.37) since no description was provided.  Of Ehrenberg's (1837b) illustrations, only pl.1, fig.4 is of a single specimen, which thus has subsequently been accepted as the holotype.  The specimen illustrated by Sarjeant (1967b, fig.3) as the holotype appears to be a different specimen.  Age: Late Cretaceous.
