Catalog entries: Margachitininae
Original description: Diagnosis: Glabrous Desmochitinidae (vesicle surface smooth, shagreen-like, or microtuberculate); chamber spheroidal-lenticular to cylindro-ovoid; collar may be present or absent; copula always developed, ending in a peduncular disc of variable width; inter-chamber connections very resistant.
Distinguishing features:
Parent taxon (Desmochitinidae): no neck
This taxon: copula
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
