Catalog entries: Conochitinidae
Original description: Family Conochitinidae n. fam.
Generally conical in shape; the greatest diameter is near the distal end.
This rather morphologically diverse family is closely related to the previous family (e.g., Conochitina micracantha and Conochitina lagenomorpha), but also shows affinities with the next family, the Desmochitinidae.
Eisenack, 1931
Distinguishing features:
Parent taxon (ct_main):
This taxon: flexure inconspicuous
Emended description:
This family includes five subfamilies: Conochitininae, Belonechitininae, Tanuchitininae, Eremochitininae, and Spinachitininae.
Paris, 1981
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 Early Ordovician Epoch (471.26-486.85Ma, 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
