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.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source: Total of range of species in this database
First occurrence (base): at top of No known fossil record modern (100% up, 0Ma, in "Holocene" stage). Data source: Total of range of species in this database

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: this is a higher taxon page so Neptune data is not plotted. For the customisable plot option go to a genus page
