Where: France (47.7° N, 7.5° E: paleocoordinates 47.1° N, 4.0° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Middle Member (Salt Formation), Early/Lower Oligocene (33.9 - 28.4 Ma)

• "In spite of abundant fossils, index fossils are rare and, hence, the stratigraphical position of the Salt Formation members has not been totally clarified yet. The most authors regard the Fossiliferous Zone as Earliest Oligocene [29]. Schuler [43] postulates the lower part of the member to be Latest Eocene in age. A biostratigraphical age based on mammals in the hanging Haustein member (Upper Salt Formation) of the ‘Rebberg’ quarry about 35 m above the horizon of discovery covers the time interval of the Mammal Reference Level MP21 and corresponds to the Lower Stampian and Upper Priabonian, thus coinciding with Stehlin‘s ‘Grande coupure’ [47]. So the stratigraphical position of the Fossiliferous Zone member seems to be close to the Eocene–Oligocene boundary." Wappler et al., 2005
