- Rang

- Kurzbeschreibung
-
The Early Toarcian is characterized almost worldwide by black shales (among which the well-known «Posidonienschiefer» of Southern Germany, and the French «schistes-carton») with an ammonite fauna composed mainly of dactylioceratids, harpoceratids and early hildoceratids.

Toarcian Oceanic Anoxic Event
- Rang
- OAE
- Status
- informeller Begriff
- Kurzbeschreibung
-
Major oceanic anoxic event of the Early Toarcian (around 183 Ma ago), documented by black shale deposits found on all major continents (no oceanic drilling cores have recovered black shales of this age as there is little or no Toarcian ocean crust remaining in the world ocean). This event correlates with a marine extinction event.
