Discoaster caulifloris

Variant: Discoaster caulifloris is regarded here as a variant of Discoaster exilis.
I.e. It is a subjective junior synonym, but some workers many find it useful for some studies (e.g. experienced biostratigraphers working with abundant, well preserved material), but for most purposes differentiating it is not reccomended. Please do use the comments section at the bottom of this page if you wish to discuss this interpretation

Hi Jeremy, there is an error in the name of this species. It's D. caulifloris and not D. cauliflorus.

Cheers, Alessandro
