Balaniger

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

Daughter taxa (time control age-window is: 0-800Ma)
				Balaniger virgulosa 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)

Taxonomic 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:
Parent taxon (Papposphaeraceae): Narrow-rimmed muroliths, mostly with prominent central structures.
This taxon: Coccolith distal rim with separated elements
Coccosphere dimorphic - spines only on some coccoliths, calyx of four rods
