Taxonomy

Citation: Desmochitininae Paris, 1981
Taxonomic rank: subfamily
Basionym: Desmochitininae Paris, 1981
Type species: Genus Desmochitina

Catalog entries: Desmochitininae

Original description: Diagnosis: Desmochitinidae with a smooth vesicle surface (which may be polished, felt-like, spongy, or granular); chamber lenticular, spheroidal, ovoid, cylindroid, or conoid; copula absent or present; collar differentiated or not; inter-chamber connections sometimes resistant.

Distinguishing features:
Parent taxon (Desmochitinidae): no neck
This taxon: glabrous

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 Early Frasnian Substage (100% up, 376.3Ma, in Frasnian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Early Ordovician Epoch (471.26-486.85Ma, base in Tremadocian 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
