Taxonomy:
Distinguishing features:
Parent taxon (Scyphosphaera): Coccospheres with Pontosphaera-like body coccoliths and equatorial coccoliths with rims elevated into vase-like structures (lopadoliths).
This taxon: Lopadoliths - large gently-flaring or parallel sided; R-unit only extends to about one third height of lopadolith
