Taxonomy
Citation: Globigerina d’Orbigny, 1826Rank: GenusType species: Globigerina bulloides d’Orbigny, 1826Taxonomic discussion: The genus Globigerina is represented by several taxa in the Oligocene-Recent. It first appears in the middle Eocene where it is relatively uncommon. It undergoes a radiation in the Oligocene.
[Olsson et al. 2006]
Catalog entries:
Globigerina
Distinguishing features: Low trochospirally enrolled, globose test; 3-5, globular chambers in final whorl.
Aperture interiomarginal, umbilical, a high arch bordered by a thin rim-like lip or thick imperforate lip.
Wall spinose; spines supported by spine collars which coalesce to form ridges.
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
Phylogenetic relations: The origin of Globigerina is uncertain. In wall texture it appears closest to Subbotina roesnaesensis n. sp., which has a ruber-type cancellate wall texture with spine collars (first observed in its ancestral species Subbotina triangularis in Zone P4).
[Olsson et al. 2006]
Most likely ancestor: Subbotina - at confidence level 0 (out of 5). Data source: .
Likely descendants: Beella; Globigerinella; Sphaeroidinellopsis;
