Taxonomy

Citation: Spinachitininae Paris, 1981
Taxonomic rank: subfamily
Basionym: Spinachitininae Paris, 1981
Type species: Genus Spinachitina

Catalog entries: Spinachitininae

Original description: Diagnosis: Conochitinidae bearing a crown of simple or branched appendages on a sharp aboral margin, coinciding with the maximum diameter of the chamber; chamber cylindro-conoidal; chains are currently unknown.

Distinguishing features:
Parent taxon (Conochitinidae): flexure inconspicuous
This taxon: processes

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 Givetian Substage (100% up, 383.1Ma, in Givetian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Late Silurian Epoch (419.00-432.93Ma, base in Sheinwoodian 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
