Taxonomy

Citation: Globorotaloides oveyi Buckley 1973
taxonomic rank: Species
Basionym: Globorotalia (Clavatorella) oveyi Buckley 1973
Synonyms:
Taxonomic discussion: Saito et al. (1981) considered G. oveyi synonymous with G. hexagonus, whilst Kennett & Srinivasan 1983 considered it a variant. However, considering the distinct morphology of G. oveyi, its occurrence in the plankton and our own observations from the plankton (Fig. 7), we see no grounds on which to reject G. oveyi as a distinct species, but note that this decision requires confirmation by genetic data.

Distinguishing features:
Parent taxon (Globorotaloides): Trochospiral test, ovate to spherical chambers; final chamber often small/bulla-like; cancellate wall.
This taxon: Like G. hexagonus but with curved dorsal sutures and more compresed chambers

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.

Description

Biogeography and Palaeobiology

Most likely ancestor: Globorotaloides hexagonus - at confidence level 2 (out of 5). Data source: Brummer & Kucera 2022 do not discuss the likely ancestor but given that it is morphologically very close to the long ranging species G. hexagonus it is reasonable to infer this is the most likely ancestor [editor's comment - JRY 2022].

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source: Buckley 1973
First occurrence (base): within no known fossil record modern (0.00-0.00Ma, base in "Holocene" stage). Data source:
