Lochriea is an extinct genus of conodonts.
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
