Citation: Globigerinella calida (Parker, 1962)

Basionym: Globigerina calida Parker, 1962

Synonyms:

Globigerina calida calida - e.g. Bolli & Premoli Silva 1973
Bolliella calida calida - e.g. Chaproniere et al. 1994

Variants:

Globigerina calida praecalida Blow 1969 [according to Kennett & Srinivasan 1983]

Taxonomic discussion: Erected by Parker (1962) to differentiate smaller, less planispiral forms with radially elongated chambers from the more planispiral and larger Globigerinella siphonifera. The two species have a distinct ecology, and the G. calida morphology is associated with a specific genetic lineage within the genetically diverse Globigerinella (Weiner et al., 2015), justifying the retention of this species. However, the morphological separation from G. siphonifera is often gradual and the identification is confounded by the existence of Globigerinella radians, making it difficult to apply the species concept consistently (Al-Sabouni et al., 2018). [Brummer & Kucera 2022]

Distinguishing features:
Parent taxon (Globigerinella): Test initially trochospiral, becoming nearly planispiral; globular to ovate chambers; aperture umbilical; fine spines cover the test
This taxon: Trochospiral coiling & slightly radially elongate chambers

Description

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

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]

Biogeography and Palaeobiology

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

In modern oceans an abundant, temperate water, species [SCOR WG138]

Map of distribution from ForCenS database

Aze et al. 2011 ecogroup 3 - Open ocean thermocline. Based on comparison with other species of the genus

Ge. calida differs from Globigerina (Gg.) bulloides by its ovate to radially elongate chambers and umbilical-extraumbilical aperture and from Ge. siphonifera 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. siphonifera during the Early Pliocene. [Kennett & Srinivasan 1983 - but with aequilateralis changed to siphonifera]

Biostratigraphic distribution

Geological Range:
Notes: Bolli & Premoli Silva 1973 recorded the FAD of G. calida calida as a useful event in the Late Pleistocene, this was confirmed by Chapronniere et al. 1994. Based on this Wade et al. (2011) included it as an additional event. However this requires separation of G. calida from G. praecalida which do not do here as G. calida is not recognised in the modern plankton.
Last occurrence (top): Extant. Data source: present in the plankton (SCOR WG138)
First occurrence (base): in upper part of N19 zone (64% up, 4.7Ma, in Zanclean stage). Data source: Kennet & Srinivasan 1983
