Phoberocysta ceratioides

"ceratioides" (Deflandre, 1937b, p.66–67, pl.12 [al. pl.9], figs.7–8) Davey and Verdier, 1971, p.26.  Holotype: Deflandre, 1937b, pl.12 (al. pl.9), figs.7–8; Fensome et al., 1991, fig.1 — p.601; fig.1 — p.605.  NOW Xenascus.  Originally Hystrichosphaera, subsequently Pseudoceratium, thirdly Spiniferites, fourthly Phoberocysta, fifthly (and now) Xenascus.  Taxonomic junior synonyms: Endoceratium (now Xenascus) perforatum, according to Davey and Verdier (1971, p.27) — however, Yun Hyesu (1981, p.62) retained Xenascus perforatus; Xenascus australensis, according to Davey and Verdier (1971, p.26) — however, Lentin and Williams (1985, p.374) retained Xenascus australensis; Odontochitina blastema, according to Davey and Verdier (1971, p.27) — however, Stover and Helby (1987a, p.128) retained Odontochitina (as Xenascus) blastema.  This combination was not validly published in Millioud (1969, p.432), since that author did not clearly use the name Phoberocysta ceratioides.  Age: Senonian.

Parent: Phoberocysta
