Taxonomy:

Citation: Solisphaera helianthiformis Bollmann et al., 2006
taxonomic rank: Species

Distinguishing features:
Parent taxon (Solisphaera): Coccoliths without radial lath cycle; coccosphere dome-shaped, polymorphic
This taxon: dBCs flat; CCs with tall triangular protrusions; pBCs flat, heavily-calcified
