NB The short diagnoses are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They have initially been copied from the diagnostic characters/distinguishing features sections of the Eocene and Paleocene Atlases, they will be edited as the site is developed.


Diagnostic characters: Ventroconical, steep conical umbilical side, spiral side flat to slightly concave, acutely keeled, heavily pustulate test

Aperture: : Interiomarginal umbilical-extraumbilical low-arched slit [Aze 2011, based on D. R. M. Stewart unpublished data]

Wall type: Non-spinose; Smooth [Aze 2011]

Biogeography and Palaeobiology

Isotope paleobiology: Aze et al. 2011 ecogroup 4 - Open ocean sub-thermocline. Based on comparison with other species of the genus

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant Data source: Not recognised by WG138 but recorded as extant by Aze et al. 2011
First occurrence (base): in upper part of PT1a subzone (69% up, 1Ma, in Gelasian stage). Data source: Wade et al. (2011), additional event; position within zone determined by linear interpolation from data in table 1 of Wade et al. (2011).
