Classification: Coccolithophores -> Holococcoliths -> tubeless -> fried egg monomorphic -> Acanthoica quattrospina HOL
Sister taxa: A. quattrospina HOL, s. aff. quattrospina HOL,

Distinguishing features: single-humped protrusion


Taxonomy:

Notes & discussion: This holococcolith phase was first described in Cros et al. 2000 and was never described as a separate speceis 

Farinacci & Howe catalog pages:

Distinguishing features: single-humped protrusion


Morphology remarks:
BCs solid disk one crystallite high, possibly with central opening; conical mound in centre.
CFCs similar to BCs but more elevated, dome-shaped.
