Taxonomy

Citation: Urochitininae Paris, 1981
Taxonomic rank: subfamily
Basionym: Urochitininae Paris, 1981
Type species: Genus Urochitina

Catalog entries: Urochitininae

Original description: Diagnosis: Lagenochitinidae with an ovoid, smooth vesicle; neck sometimes ornamented (with simple or anastomosed hairs); copula shaped like a peduncle, very elongated; chains fairly fragile.

Distinguishing features:
Parent taxon (Lagenochitinidae): flexure conspicuous
This taxon: copula

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 Famennian Substage (100% up, 361.8Ma, in Famennian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Ordovician Period (443.07-486.85Ma, 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
