Areosphaeridium pectiniforme

"Areosphaeridium pectiniforme" (Gerlach, 1961, p.195-196, pl.28, fig.14; text-fig.18) Stover and Evitt, 1978, p.20.

EMENDATIONS: Sarjeant, 1984b, p.83-84,86, as Areosphaeridium pectiniforme; Stover and Williams, 1995, p.114, as Enneadocysta pectiniformis.

TYPE: Holotype: Gerlach, 1961, pl.28, fig.14; Sarjeant, 1984b, pl.1, fig.2; pl.4, fig.2.

HISTORY: NOW: Enneadocysta. Originally Baltisphaeridium (Appendix A), subsequently Cleistosphaeridium, thirdly Areosphaeridium, fourthly Areosphaeridium?, fifthly (and now) Enneadocysta. Questionable assignment: Stover and Evitt (1978, p.20) - however, Sarjeant (1984b, p.83) included this species in Areosphaeridium without question.

SYNONYM(S): Taxonomic junior synonym: Areosphaeridium (now Enneadocysta) multicornutum, according to Sarjeant (1984b, p.83-84,86) - however, Stover and Williams (1995, p.112) retained Areosphaeridium (as Enneadocysta) multicornutum.

AGE: mid Oligocene.
