Catalog entries: Conochitininae
Original description: Diagnosis: Conochitinidae with a smooth vesicle surface (which may be polished, felt-like, or smooth); chamber conical, club-shaped to cylindroid; aboral margin rounded or pointed; mucron present, sometimes well developed; inter-chamber connections very fragile.
Distinguishing features: glabrous
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.
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
