Citation: Ericsonia aliquanta Bown 2016
Rank: Species

Distinguishing features: medium-sized (5–9μm), circular to subcircular with relatively wide central area

Farinacci & Howe catalog pages: E. aliquanta *


Morphology: Medium-sized (5–9μm), circular to subcircular Ericsonia coccoliths with a central area width similar to or greater than the rim width.
Distinguished from E. robusta by its smaller size, from E. orbis by its larger size and from E. subpertusa by its relatively wider central area. Previous work most likely included these forms in E. robusta.
