Where: Victoria, Australia (38.3° S, 144.3° E: paleocoordinates 49.7° S, 142.5° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Jan Juc Formation, Early/Lower Miocene (23.0 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From lithostratigraphic units that may include the Jan Juc Fm, which conformably overlies the Demons Bluff Fm (Early-Late Oligocene), laterally correlates to Point Addis and Waurn Ponds Fms, and the Puebla Fm, which is conformably overlain by the Zeally Limestone (Early Miocene) and Fyansford Fm (Middle Miocene). AGE: earliest Early Miocene (late Janjukian-early Longfordian) 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).
