Taxonomy:

Citation: Pappomonas sp. type 3 Cros & Fortuño, 2002
taxonomic rank: type

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: Like Papposphaera sp. type 3 but BCs with simple spine, no calyx.

Morphology:

NB The coccoliths of this species are similar to those of Papposphaera bourrellii, and Papposphaera sp. type 3 of Cros & Fortuño (2002). They differ essentially in having body coccoliths with a central node rather than a spine.

Size:
Coccosphere 12-13 µm; BCs ca.1.0 µm long
