Distinguishing features:
Parent taxon (Urochitininae): copula
This taxon: ovoid to club-like body and a peduncle on the apex.

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
