Pareodinia nuda
From dinoflaj2
"?nuda" Downie, 1957, p.424, pl.20, fig.11; text-fig.2e ex Sarjeant, 1967b, p.254. Holotype: Downie, 1957, pl.20, fig.11. Originally Palaeoperidinium (name not validly published), subsequently Pareodinia, thirdly Pareodinia?. Questionable assignment: Below (1990, p.66) as a "nomen dubium". Taxonomic senior synonym: Pareodinia ceratophora, according to Wiggins (1975, p.103) and Kunz (1990, p.13). The name Palaeoperidinium nudum Downie was not validly published in Downie (1957) since the generic name Palaeoperidinium was not validly published until 1957. Williams et al. (1998, p.467) accepted Sarjeant's (1967b) indirect reference to Downie (1957) as indication of a type (I.C.B.N. Article 37.1). Age: Late Kimmeridgian.
Parent: Pareodinia
