Gündlkofen (Miocene to of Germany)

Where: Bayern, Germany (48.5° N, 12.0° E: paleocoordinates 48.8° N, 10.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: MN 5 to MN 5 (16.0 - 12.8 Ma)

• Upper Fresh-water Molasse, "according to gastropods (Blissenbach 1957, S.24) the fossil locality is of Tortonian, rather than Sarmatian age. According to the Cricetids, which are very similar to Sandelzhausen, no exact age can be determined." Based on fossil and lithological evidence, Gall (1980), following Meier (1965), related it to the lower section of the Nördlicher Vollschotter, which in turn is a member of the Upper Freshwater Molasse ("Obere Süßwassermolasse", OSM; Abdul Aziz et al. 2008). As such, Gall (1980) suggested an age of roughly 15 Ma for the site, correlating it with the Middle Silvana-beds (“Silvanaschichten”) and the Langhian/Badenian stages (Middle Miocene; MN 5-6 European Mammal Neogene zones).
