Balaniger


Classification: Coccolithophores -> Coccolith families inc sed -> Papposphaeraceae -> Balaniger
Sister taxa: Balaniger, Formonsella, Kataspinifera, Pappomonas, Papposphaera, Picarola, Pocillithus, Pseudowigwamma, Quaternariella, Ventimolina, Vexillarius, Wigwamma,

Daughter taxa: (blue => in age window 0-800Ma)
Central area with concentric rings of crystallites, rim elements separated and so wall is discontinuous.
CFC process ca. 1.5 µm high, with long stem supporting four (occasionally 2or 3) radiating rods ca. 0.5 µm long.

Taxonomy:

Citation: Balaniger Thomsen & Oates 1978
Rank: Genus
Type species: Balaniger balticus Thomsen & Oates (1978) (=B. virgulosa)
Notes & discussion: The species B. virgulosa was formerly included in Pappomonas but the holococcolith phase is clearly distinctive and heterococcolith rim arguably distinctive (Thomsen & Ostergaard 2014)

Distinguishing features: Coccolith distal rim with separated elements
Coccosphere dimorphic - spines only on some coccoliths, calyx of four rods
