The Werfen Formation is a geologic formation in the Southern Limestone Alps and Dinaric Alps of Austria, Bosnia and Herzegovina, and Italy. It preserves fossils dating back to the Triassic period.[1]

Fossil content

The formation has provided numerous fossils typical of a shallow lagoon environment, including:

Griesbachian aged layers of the formation also preserve an unexpectedly diverse ichnotaxon assemblage, including the ichnogenera Catenichnus, Helminthopsis, Lockeia, Palaeophycus, Planolites, Rhizocorallium, Spongeliomorpha, Taenidium and Thalassinoides.[3]
