Short diagnosis: trochospiral coiling & radially elongate chambers


Diagnostic characters: Low trochospiral, equatorial periphery strongly lobulate

Aperture: : Umbilical-extraumbilical with a narrow lip [Aze 2011, based on Kennett & Srinivasan 1983]

Coiling direction (in extant population): mixed

Wall type: Spinose; Hispid [Aze 2011]

Test morphology: Test low trochospiral, equatorial periphery strongly lobulate; axial periphery rounded, chambers subglobular initially, ovate, to rapidly elongate in later stages; 4 to 5 rapidly enlarging chambers in the final whorl; sutures distinct, radial, depressed; surface densely perforate, finely hispid; aperture umbilical, becoming umbilical-extraumbilical , a rather low arch with a narrow lip. [Kennett & Srinivasan 1983]

Size: >150µm

Biogeography and Palaeobiology

Geographic distribution: Tropical to warm subtropical. [Kennett & Srinivasan 1983]

Isotope paleobiology: Aze et al. 2011 ecogroup 3 - Open ocean thermocline. Based on light ∂13C and relatively heavy ∂18O Cited sources (Aze et al. 2011 appendix S3): this study

Phylogenetic relations: Ge. calida differs from Globigerina (Gg.) bulloides by its ovate to radially elongate chambers and umbilical-extraumbilical aperture and from Ge. aequilateralis by its less involute test, lower spire, and more lobulate outline. Loose coiling of the test and well-separated chambers in the final whorl suggest a relationship with Ge. adamsi, which differs in exhibiting digitate chambers.
Ge. calida appears to have evolved from Ge. aequilateralis during the Early Pliocene. [Kennett & Srinivasan 1983]

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant Data source: present in the plankton (SCOR WG138)
First occurrence (base): in upper part of PT1b subzone (64% up, 0.2Ma, in Ionian 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).
