Use in stratigraphyEdit

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
