Brunstatt, horizon f (Oligocene of France)

Where: France (47.7° N, 7.3° E: paleocoordinates 47.1° N, 3.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Oligocene (33.9 - 28.4 Ma)

• Lutz (1997) and Mai (1995) assign the age of Brunstatt and Kleinkems to the Lower Oligocene, but Mai (1995) also allocated Brunstatt to the Mammal Reference Level MP20 which corresponds to the Priabonian (37.2–33.9 Ma) in the latest part of the Eocene. Thus, the stratigraphical position of Brunstatt and Kleinkems seems to be close to the Eocene-Oligocene boundary.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified marl

• Deposited on the shore of a very large shallow saline lake (with an area of several hundred square kilometres) with episodical intrusion of fresh water.

Size classes: macrofossils, mesofossils

Preservation: mold/impression, adpression
