Globotruncanida

Citation: Globotruncanida Arz, Arenillas & Gilabert in Arenillas et al. 2022
taxonomic rank: order
Type species: Globotruncana Cushman, 1927

Current identification/main database link: Mesozoic Planktonic Foraminifera


Original Description

Diagnosis. Test trochospiral or planispiral. Peripheral margin without keel, or with one or two keel. Aperture bordered by a lip or protected by a porticus or a tegillum, rarely by a bulla. Finely perforate to macroperforate. Wall surface smooth, pore-mounded, pitted, reticulate, hispid, pustulate, muricate, rugose, or costate. Wall hyaline calcitic, but early forms may be aragonitic.

Extra details from original publication
Superfamilies included. Abathomphaloidea Arz, Are- nillas & Gilabert n. superfam.; Favuselloidea Longoria, 1974; Hedbergelloidea Longoria & Gamper, 1975; Glo- botruncanoidea Brotzen, 1942; Planomalinoidea Bolli, Loeblich & Tappan, 1957; Rotaliporoidea Sigal, 1958; Rugoglobigerinoidea Subbotina, 1959.

Justification: If the hypothesis that Cenozoic globigerinids evolved after the KPB extinction from the benthic genus Caucasina is verified, as proposed by Brinkhuis and Zachariasse (1988) and Arenillas and Arz (2017), then Mesozoic planktic foraminifera are phylogenetically disconnected from those of the Cenozoic. Even excluding heterohelicids as already postulated by Fursenko (1958) and BouDagher-Fadel (2012, 2015), the order Globigerinida becomes polyphyletic if the spiral Mesozoic taxa are included. It is therefore necessary to separate the latter in a new order, which we have called Globotruncanida, because the genus Globotruncana Cushman, 1927, and the family Globotruncanidae Brotzen, 1942, are the ones that best characterize it. Consequently, it is also necessary to emend the order Globigerinida.

This new order includes Conoglobigerina, the first planktic foraminifera to appear (if Sphaerogerina is excluded), as well as all its descendants (Fig. 1). Consequently, the order Globotruncanida appeared in the Bajocian (Middle Jurassic), and includes 7 superfamilies and 20 families. The globotruncanids reached at the Maastrichtian the largest test size of all planktic foraminifera, up to 1 mm in diameter as in the case of Contusotruncana Korchagin, 1982. For comparison, Cenozoic and current species do not exceed 600 μm in diameter.
