Taxonomy

Citation: Eremochitininae Paris, 1981
Taxonomic rank: subfamily
Basionym: Eremochitininae Paris, 1981
Type species: Genus Eremochitina Taugourdeau & de Jekhowsky, 1960

Catalog entries: Eremochitininae

Original description: Diagnosis: Glabrous Conochitinidae (surface smooth or roughened); chamber club-shaped to sub-cylindrical; aboral margin rounded; membranous sleeve, tubular, bulbous, or detached, extending from the aboral pole; inter-chamber connections are fragile when present.

Distinguishing features:
Parent taxon (Conochitinidae): flexure inconspicuous
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 Wenlock Epoch (100% up, 426.7Ma, in Gorstian 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
