Trichodinium ciliatum

ciliatum (Gocht, 1959, p.65, pl.8, figs.5–6) Eisenack and Klement, 1964, p.811.  Holotype: Gocht, 1959, pl.8, fig.5; Jan du Chêne et al., 1986a, pl.121, figs.9–13.  Originally Apteodinium, subsequently (and now) Trichodinium.  Taxonomic junior synonym: Trichodinium castanea, by implication in Clarke and Verdier (1967, p.19), who believed Trichodinium castanea to be the senior name — however, Harding (1990b, p.38) retained the two species.  Age: late Hauterivian.

Parent: Trichodinium
