Taxonomy

Citation: Parisochitina Boumendjel, 1985
Taxonomic rank: genus
Basionym: Parisochitina Boumendjel, 1985
Type species: Parisochitina perforata Boumendjel, 1985

Catalog entries: Parisochitina

Original description: Diagnosis: Angochitininae with an ovoid body, equipped with a fairly short subcylindrical neck; oral opening surrounded by a flared collar; flexure and shoulder weakly marked; ornamentation consisting of a reticulum covering most of the body and extending aborally into a tubular perforated structure.

Distinguishing features:
Parent taxon (Cyathochitininae): carina
This taxon: ovoid to club-like chamber partly covered with a reticulum extending beyond the base in a meshlike sleeve.

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

Biostratigraphic distribution

Geological Range:
Last occurrence (top): at top of Late Devonian Period (100% up, 359.3Ma, in Early Carboniferous stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Frasnian Stage (371.10-378.90Ma, base in Frasnian stage). Data source: Total of ranges 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
