Kossen B6 (Triassic of Austria)

Where: Austria (47.7° N, 12.5° E: paleocoordinates 31.1° N, 16.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Sagenites reticulatus zone, Hochalm,Unit2 Member (Kossen Formation), Rhaetian (208.5 - 201.3 Ma)

• Age assignment changed from Norian to Rhaetian by W. Kiessling. Following the re-definition of the Rhaetian stage by Dagys and Dagys (1994, Global correlation of the terminal Triassic: Memoires de Geologie (Lausanne), v. 22, p. 25-34) the Kossen Formation is now considered to be entirely Rhaetian in age (McRoberts pers. comm., Kiessling et al. 2007).

• bed-level stratigraphic resolution

Environment/lithology: carbonate

• Gervillia-Atreta biofacies
• bioclastic limestone
