Where: Victoria, Australia (37.7° S, 142.0° E: paleocoordinates 46.6° S, 140.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Muddy Creek Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Muddy Creek, which interfingers the Gellibrand Fm (Early Miocene-Middle Miocene) in Central Otway Basin. AGE: Middle Miocene (Balcombian) according to Beu and Darragh (2001). STRATIGRAPHIC POSITION: From multiple localities and horizons, hence assigned to a "formation" scale. NOTES: From antiquated publication that predates establishment of region lithostratigraphic framework. Assignments to lithostratigraphic unit and age are based on interpretation by enterer on the basis of cross-referening localities and taxa to more recent publications (e.g. Darragh 1970, Darragh 1986, and in particular Beu and Darragh 2001).
