Biogeography and Palaeobiology


Geographic distribution

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

[SCOR WG138]


Isotope paleobiology
Aze et al. 2011 ecogroup 3 - Open ocean thermocline. Based on light δ13C and relatively heavy δ18O. Sources cited by Aze et al. 2011 (appendix S3): Schneider & Kennett (1996)

Phylogenetic relations
Barbieri (1967) considered Gr. (G.) puncticulata to be closely related to Gr. crassaformis. Stainforth et al. (1975) suggested that Gr. (G.) puncticulata may be a descendant of Globorotalia subscitula, and Berggren (1977b) suggested that its ancestry is from Gr. cibaoensis. Detailed biometric studies of this lineage by Malmgren and Kennett (1981) demonstrate that Gr. (G.) puncticulata evolved in the Early Pliocene from Gr. (G.) conomiozea via Gr. (G.) sphericomiozea and in turn gave rise to Gr. (G.) inflata during the Late Pliocene. Gr. (G.) puncticulata is distinguished from Gr. (G.) inflata by having not fewer than 4 chambers in the final whorl,in exhibiting less inflation, and a smaller aperture. For more detailed information on this lineage, see Malmgren and Kennett (1981). [Kennett & Srinivasan 1983]

Most likely ancestor: Globoconella terminalis - at confidence level 3 (out of 5). Data source: Wei 1994, fig.1 - (Wei considered terminalis-> sphericomiozea -> puncticulata as lineage. Since sphericomiozea is now considered a synonym of puncticulata the lineage simplifies to terminalis -> puncticulata).
Likely descendants: Globoconella inflata; plot with descendants

Consider referencing Scott et al. 2007: Globorotalia puncticulata: population divergence, dispersal and extinction related to Pliocene-Quaternary water masses. Marine Micropaleontology 62: 235-253.

Dear Dr. Scott

That you for taking the time to comment on this, all suggestions help. I will add that shortly.

Pl.27, figs. 1-3 from K&S, 1983 are G. sphericomiozea not G. puncticulata

Thank you for the comment. Those images were indeed identified by Kennett & Srinivasan 1983 as G. sphericomiozeabut we are following Lam & Leckie 2020 here in regarding sphericomioziea and puncticulata as synonyms. That is, of course, a subjective opinion but it seems reasonable.
