Classification: Coccolithophores -> Discoasterales -> Fasciculithaceae -> Diantholitha -> Diantholitha mariposa
Sister taxa: D. mariposa,

Distinguishing features: See generic diagnosis


Taxonomy:

Citation: Diantholitha mariposa Rodriguez & Aubry in Aubry et al. 2011

Geological Range:
Notes: Confined to a short interval within NP4 - this is best documented in Monechi et al. 2013, who indicate the range is approximately equivalent to magnetochron C27n
Last occurrence (top): in upper part of NP4 zone (62% up, 62.2Ma, in Selandian stage). Data source: Monechi et al. (2013, fig 6)
First occurrence (base): in mid part of NP4 zone (50% up, 62.4Ma, in Danian stage). Data source: Monechi et al. (2013, fig 6)
