Peridinium comatum Appendix B

"comatum" Morgenroth, 1966b, p.1, pl.1, figs.1–2.  Holotype: Morgenroth, 1966b, pl.1, fig.1.  NOW Phthanoperidinium.  Originally Peridinium (Appendix B), subsequently (and now) Phthanoperidinium.  Taxonomic junior synonyms: Phthanoperidinium tritonium, according to Bujak in Bujak et al. (1980, p.72); however, Fensome et al. (2009, p.54–55) considered Phthanoperidinium tritonium to be a taxonomic junior synonym of Phthanoperidinium coreoides; Hystrichogonyaulax (now Phthanoperidinium) coreoides, according to Stover and Evitt (1978, p.118) — however, Benedek and Sarjeant (1981, p.328–330) retained Phthanoperidinium coreoides.  Eaton (1976, p.294) also proposed this combination.  Age: early Oligocene.
