Sister taxa: P. borealis, P. flabellifera, P. garrisonii, P. weddellensis ⟩⟨ P. sp. type 1, P. sp. type 4, P. sp. type 5 ⟩⟨ P. sp.


Citation: Pappomonas garrisonii Thomsen & Ostergaard 2014
taxonomic rank: Species

Distinguishing features:
Parent taxon (Pappomonas): Coccolith distal rim serrated - elements pentagonal;
Coccosphere dimorphic or trimorphic. Processes only on CFCs coccoliths. Calices with 2-fold symmetry
BCs without axial spine or node

This taxon: CFCs with axial cross, spine and flat calyx of two similar, diverging blades each with central rod
BCs with 5 longitudinal bars and one crossbar
AACs like CFCs but with lower spine and smaller clayx, may occur around coccosphere
