Hormosinana

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.

Taxonomy

Citation: Hormosinana Mikhalevich, 1992
Taxonomic rank: subclass

Catalog entries: Hormosinana

Distinguishing features:
Parent taxon (bf_main):
This taxon: uniserial or simply coiled, terminal apertures

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.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source:
First occurrence (base): within Kimmeridgian Stage (149.24-154.78Ma, base in Kimmeridgian stage).

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
