Acanthoica quattrospina HOL


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

Taxonomy:

Citation: Acanthoica quattrospina Lohmann, 1903 HOL
Rank: Form
Notes & discussion: This holococcolith phase was first described in Cros et al. 2000 and was never described as a separate speceis 

Distinguishing features: single-humped protrusion

Farinacci & Howe catalog pages: ,


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.
