Taxonomy:

Citation: Papposphaera bourrellii Thomsen & Buck, 1998
taxonomic rank: Species

Distinguishing features:
Parent taxon (Papposphaera): Coccolith distal rim serrated - elements pentagonal;
Coccosphere varimorphic, or dimorphic. All coccoliths have spines but CFCs typically have longer spines and larger calices.

This taxon: Central areas with axial cross
Processes ca 3.5 µm long with calyx-like distal appendage.
