Original description: Diagnosis: Angochitininae with an ovoid body, equipped with a fairly short subcylindrical neck; oral opening surrounded by a flared collar; flexure and shoulder weakly marked; ornamentation consisting of a reticulum covering most of the body and extending aborally into a tubular perforated structure.
Distinguishing features:
Parent taxon (Cyathochitininae): carina
This taxon: ovoid to club-like chamber partly covered with a reticulum extending beyond the base in a meshlike sleeve.
Geological Range:
Last occurrence (top): at top of Late Devonian Period (100% up, 359.3Ma, in Early Carboniferous stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Frasnian Stage (371.10-378.90Ma, base in Frasnian 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
