Elphidium

NB This site is under active development, current content in the main database is primarily from Bolli et al 1994, Hayward et al. 2012, Holbourn et al. 2013, Holbourn and Kaminski 1997, Alegret & Thomas 2001, and Katz et al. 2003. It is intended to expand and develop this to provide rather comprehensive coverage of Mesozoic and Cenozoic deep-sea benthic 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.

Biogeography and Palaeobiology


Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source: Total of range of species in this database
First occurrence (base): within Miocene Epoch (5.33-23.03Ma, base in Aquitanian stage). Data source: Total of range of species in this database

Plot of occurrence data:
NB The ranges given for genera and higher taxa are the total ranges of species included in that taxon in this database - so the true total range of the taxon will usually be longer
