Cordosphaeridium gracile forma areolatum
Cordosphaeridium gracile forma areolatum (Eisenack, 1954b, p.67, pl.12, fig.21) Williams and Fensome, 2016, p.140. Holotype: Eisenack, 1954b, p.67, pl.12, fig.21.
Originally Hystrichosphaeridium inodes subsp. gracile forma areolatum, subsequently (and now) Cordosphaeridium gracile forma areolatum.
Williams and Fensome (2016, p.140) noted that the distinctive surface texture described by Eisenack (1954b) may be a preservational artifact, and hence they recommended that this taxon be restricted to its type.
Age: Oligocene.
