Hystrichosphaeridium oligacanthum ssp. stella
Hystrichosphaeridium oligocanthum ssp. stella W. Wetzel, 1952
Now Surculosphaeridium phoenix ssp. stella. Originally Hystrichosphaeridium oligacanthum ssp. stella, subsequently Baltisphaeridium oligacanthum ssp. stella, thirdly Cleistosphaeridium? oligacanthum ssp. stella, fourthly (and now) Surculosphaeridium phoenix ssp. stella.
Holotype: W. Wetzel, 1952, pl.A, fig.4
Locus typicus: Kiel district, Germany
Stratum typicum: Paleocene
Translation W. Wetzel: Sarjeant, 1984
Original diagnosis: W. Wetzel, 1952, p. 403
Some specimens, which in other attributes do not differ from the typical species, are distinguishable from it in that the distal ends of the processes develop into two sideways-directed prongs (and thereby suggest more the usual structure of hystrichosphere processes). Also no noteworthy curving of the processes was observed.
