Taxonomy

Citation: Pellichitininae Achab, Asselin and Soufiane, 1993
Taxonomic rank: subfamily
Basionym: Pellichitininae Achab, Asselin and Soufiane, 1993
Type species: Genus Pellichitina

Catalog entries: Pellichitininae

Original description: Diagnosis: Lagenochitinidae characterized by an outer layer which is clearly separated from the wall of the chamber. The outer layer sometimes expands aborally to form a copula.

Distinguishing features:
Parent taxon (Lagenochitinidae): flexure conspicuous
This taxon: 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 Floian Stage (100% up, 471.3Ma, in Floian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Floian Stage (471.26-477.08Ma, base in Floian 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
