Use in stratigraphy

The Tournaisian, the oldest age of the Mississippian (also known as Lower Carboniferous), contains eight conodont biozones, one of which is defined by a ''Polygnathus'' species:
* the zone of ''Gnathodus pseudosemiglaber'' and '' Scaliognathus anchoralis''
* the zone of ''Gnathodus semiglaber'' and ''Polygnathus communis''
* the zone of '' Dollymae bouckaerti''
* the zone of ''Gnathodus typicus'' and ''Siphonodella isosticha''
* the zone of ''Siphonodella quadruplicata'' and '' Patrognathus andersoni'' (upper zone of ''Patrognathus andersoni'')
* the lower zone of ''Patrognathus andersoni''
* the zone of ''Patrognathus variabilis''
* the zone of ''Patrognathus crassus''
