Acanthoica quattrospina HOL

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


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.

Biology & life-cycles: Combination coccospheres with A. quattrospina HET observed by Cros et al. 2000, Cros & Fortuno 2002, Supraha et al. 2014, Triantaphyllou et al. 2016
