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.Werfen Formation at Fossilworks.org
Fossil content The formation has provided numerous fossils typical of a shallow lagoon environment, including:
Eotiaris teseroensis (a crown-group echinoid from Changhsingian aged beds of the Tesero Member) Orbicoelia sp. (a brachiopod) Teserina nerii (a brachiopod)
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.
