Diantholitha mariposa

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


Citation: Diantholitha mariposa Rodriguez & Aubry in Aubry et al. 2011
Rank: Species
Variants: The typical D. mariposa is butterfly-like in profile with the two cycles of similar size. Aubry et al. 2011 also distinguished two  other species differing primarily in the shape of the upper cycle ("calyptra") elements.

Fasciculithus sp. 1 Bernaola et al. 2009

Distinguishing features: See generic diagnosis

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)
