Gehrener Formation (Germany)

The Gehrener Schichten (German for Gehren Formation) is a geologic formation in Germany. The fluvial to lacustrine shales preserve fossils dating back to the Late Carboniferous period (Stephanian C in European stratigraphy or Gzhelian in international stratigraphy).

The following fossils were reported from the formation:^[1][2]

• Insects
  • Protelytroptera
    • Blattocoleidae
      • Blattocoleus tillyari^[3]
  • Blattodea
    • Mylacridae
      • Opsiomylacris (Opsiomylacris) densistriata^[4]
