Palaeotetradinium

PALAEOTETRADINIUM Deflandre, 1936b, p.189.  Emendations: Deflandre and Sarjeant, 1970, p.3; Stover and Evitt, 1978, p.70.  Taxonomic junior synonyms: Inversidinium and Rhombodella, both according to Stover and Evitt (1978, p.70–71) — however, Duxbury (1980, p.134–135) retained Rhombodella.  This name was not validly published in Deflandre (1934, caption to fig.6 — p.967) since no description was provided.  Type: Deflandre, 1936b, pl.9, fig.11, as Palaeotetradinium silicorum.
