Taxonomy

Citation: Belonechitininae Paris, 1981
Taxonomic rank: subfamily
Type species: Genus Belonechitina

Catalog entries: Belonechitininae

Original description: Diagnosis: Ornamented Conochitinidae (vesicle partially or completely covered with cones, spines, or hairs, either simple or multipodal, anastomosed or not, scattered or aligned in rows); chamber cylindro-conical; aboral margin rounded; mucron also present; inter-chamber connections are very fragile.

Distinguishing features:
Parent taxon (Conochitinidae): flexure inconspicuous
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 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 Late Givetian Substage (378.90-380.30Ma, base in Givetian 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
