Taxonomy:
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 and a 1 or a few extra bars
Process 2-4 µm high ending distally in four sub-parallel crystallites, each ca. 1 µm long (no real calyx).
