Taxonomy

Citation: Cenozoic planktonic foraminifera
Rank: informal group

Catalog entries: Globorotalia (Fohsella)

Distinguishing features:
Parent taxon (images):
This taxon: This is a polyphyletic gruoping including all Cenozoic planktonic foraminifera

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 large majority of included taxa are thought to have a common origin from a single surviving species after the K/Pg extinctions. Alternatively more polyphyetic origins from a range of survivors have been proposed. The biserial taxa are thought to have repeatedly evolved from benthic taxa.
