Distinguishing features:
Parent taxon (Eprolithus): Moderately tall, circular to stellate, multiradiate nannoliths with 5-9 petaloid wall-cycle elements surrounding a wide central area spanned by a median diaphragm. Typically H-shaped in side view.

Distinguishing features:
Parent taxon (Eprolithus): Moderately tall, circular to stellate, multiradiate nannoliths with 5-9 petaloid wall-cycle elements surrounding a wide central area spanned by a median diaphragm. Typically H-shaped in side view.
This taxon: Eprolithus with nine wall-elements.

Common and long ranging Eprolithus.

Size:

Most likely ancestor: Eprolithus apertior - at confidence level 1 (out of 5). Data source: implicit in taxonomy - it is suggested floralis and apertior are very closely related and since apertior occurs first it should be the ancestor .
Likely descendants: Eprolithus octopetalus; plot with descendants
