Distinguishing features: Final chambers compressed and radially elongate with multiple slender digitate extensions.

NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.
They are being edited as the site is developed and comments on them are especially welcome.

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).
