Catalog entries: Belonechitininae
Original description: Diagnosis: Ornamented Conochitinidae (vesicle partially or completely covered with cones, spines, or hairs, either simple or multipodal, anastomosed or not, scattered or aligned in rows); chamber cylindro-conical; aboral margin rounded; mucron also present; inter-chamber connections are very fragile.
Distinguishing features: spiny
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 Early Frasnian Substage (100% up, 376.3Ma, in Frasnian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within Late Givetian Substage (378.90-380.30Ma, base in Givetian 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
