Stratigraphic range: Jurassic
Type Formation

Country Austria

The Allgäu Formation is a geologic formation in Austria. It preserves fossils dating back to the Jurassic period. Initially and formally defined by Jacobshagen (1965).[1] Allgäu Formation formerly known as spotted marls (Lias-Fleckenmergel) and spotted marly limestones (Fleckenkalk) represented by dark-grey bioturbated limestones and marlstone interbeds. It represents basinal hemipelagic facies[2] common in Alpine Tethys regions of Alps, Carpathians and other mountain ranges. Several horizons of the formation are particularly rich on Ammonite fauna.
