Taxonomy

Citation: Angochitininae Paris, 1981
Taxonomic rank: subfamily
Basionym: Angochitininae Paris, 1981
Type species: Genus Angochitina Eisenack, 1931

Catalog entries: Angochitininae

Original description: Diagnosis: Ornamented Lagenochitinidae [vesicle partially or entirely covered with cones, tubercles, network, spines, simple or complex hairs, free or anastomosed, scattered or aligned in rows (or rings)]; flexure and shoulder distinct; vesicle lenticular, conoidal, ovoid or cylindroid; aboral margin rounded; mucron absent; chains fragile.

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

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 Famennian Stage (100% up, 359.3Ma, in Early Carboniferous stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Middle Ordovician Epoch (458.18-471.26Ma, base in Dapingain 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
