Pliensbachian–Toarcian (Early Jurassic) extinction in western North America ...
The Pliensbachian–Toarcian marine extinction is observable at the species and generic levels. Ammonite diversity data from Europe and parts of the Arctic suggest a multi-phased event with diversity declining over six separate intervals. The main-phase of decline begins at the Pliensbachian–Toarcian...

The Pliensbachian–Toarcian marine extinction is observable at the species and generic levels.
