Mesolouri (Eptachorion Fm) (Oligocene of Greece)

Where: Greece (40.1° N, 21.2° E: paleocoordinates 37.0° N, 18.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Eptachorion Formation, Rupelian (33.9 - 28.1 Ma)

• STRATIGRAPHIC RELATIONS: From Eptachorion Fm that overlies ophiolithic basement. Details given by Wielandt-Schuster et al. (2004). THICKNESS: From 900 m thick basal unit, within 1700 m thick section AGE: Eptachorion Fm is Late Rupelian to Early Chattian based on planktonic foraminfera, corresponding to biozones P20-P21 (Barbieri 1992) and to NP 24 (Zygojanni and Müller, 1982) based on nannoplankton. The basal part of Mesolouri, from where the gastropod fauna derives, indicates a Late Rupelian age corresponding to P21 (pers. comm., F. Rögl, in Harzhauser 2004). STRATIGRAPHIC POSITION: From basal unit.
