Palaeoperidinium granulatum Oleinik 1975

?granulatum (Oleinik, 1975, p.225-226, pl.1, figs.3-5) Lentin and Williams, 1981, p.210.  Holotype: Oleinik, 1975, pl.1, figs.3-5.  Originally Pentagonum granulatum (generic name illegitimate), subsequently (and now) Palaeoperidinium granulatum Oleinik, thirdly Palaeoperidinium oleinikii (name illegitimate).  Nomenclatural junior synonym: Palaeoperidinium oleinikii, which has the same type.  Questionable assignment: Evitt et al. (1998, p.48).  Lentin and Williams (1981, p.210; 1993, p.480) considered this name to be illegitimate, as a junior homonym of Palaeoperidinium granulatum Singh, 1964.  However, Williams et al. (1998, p.456) considered the name Palaeoperidinium granulatum Singh to be not validly published, and hence that Palaeoperidinium granulatum Oleinik must be considered a validly published and legitimate name.  Age: Late Eocene.

Parent: Palaeoperidinium
