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: Trochospiral, final chambers compressed and radially elongate with multiple slender digitate extensions

Aperture: : Primary aperture interiomarginal umbilical wide arch with rim. Supplementary sutural apertures on spiral side [Aze 2011, based on Kennett & Srinivasan 1983]

Wall type: Spinose; Cancellate [Aze 2011]

Test morphology: Test large, trochospiral, three to four chambers in the final whorl; chambers spherical initially, later becoming compressed and radially elongate with multiple, slender, digitate extensions; sutures distinct,depressed; surface densely perforate; primary aperture interiomarginal, umbilical, a wide arch with a rim; supplementary apertures over sutures of earlier chambers. [Kennett & Srinivasan 1983]

Biogeography and Palaeobiology

Geographic distribution: Tropical to warm subtropical. [Kennett & Srinivasan 1983] Low latitudes [Aze et al. 2011, based on Kennett & Srinivasan (1983)]

[SCOR WG138]

Isotope paleobiology: Aze et al. 2011 ecogroup 1 - Open ocean mixed-layer tropical/subtropical, with symbionts. Based on very heavy ∂13C and relatively light ∂18O. Sources cited by Aze et al. 2011 (appendix S3): Keller (1985); Pearson & Shackleton (1995)

Phylogenetic relations: This species evolved from Gs. sacculifer by developing multiple digitate extensions on the last few chambers in the final whorl. [Kennett & Srinivasan 1983]

Most likely ancestor: Trilobatus sacculifer - at confidence level 4 (out of 5). Data source: Kennett & Srinivasan 1983; Spezzaferri et al. 2015.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): at top of PL6 [Atl.] zone (100% up, 1.9Ma, in Gelasian stage). Data source: Wade et al. (2011), zonal marker
First occurrence (base): in upper part of PL5 [Atl.] zone (71% up, 2.6Ma, in Piacenzian 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).
