Use in stratigraphy

The Visean, the second age of the Mississippian, contains four conodont biozones, two of which are named after Lochriea species:

the zone of Lochriea nodosa
the zone of Gnathodus bilineatus
the zone of Lochriea commutata
the zone of Pseudognathodus homopunctatus

The Serpukhovian, the third or youngest age of the Mississippian, includes three conodont biozones, one of which is named after Lochriea species:

the zone of Gnathodus postbilineatus
the zone of Gnathodus bollandensis
the zone of Lochriea ziegleri
