Parent taxon (Pappomonas): Coccolith distal rim serrated - elements pentagonal;
Coccosphere polymorphic, processes on only some coccoliths. Calices with 2-fold symmetry
BCs without axial spine or node
This taxon: BCs oval with 5 longitudinal bars and one crossbar CFCs circular with cross, stem supports two elements each with wing-like blades.
Farinacci & Howe catalog pages: P. garrisonii [no catalog entry yet]
Morphology: CFCs redistributed around coccosphere, as well as occurring at flagellar pole.
Biology & life-cycles: Combination coccospheres with Turrisphaera type holococcoliths seen (Thomsen & Ostergaard 2014) and coccosphers of these holococcoliths subsequently recognised (Thomsen & Ostergaard 2015)
