Also known as Lake Frome

Where: South Australia, Australia (31.2° S, 140.2° E: paleocoordinates 46.1° S, 136.2° E)

• coordinate stated in text

When: Namba Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• The accepted age for the Namba formation has varied from late Oligocene-early Miocene. Woodburne et al. 1994 suggested a late Oligocene age for the correlated faunas of Zone A in the Etadunna Formation. Martin 1990 also suggested that an early Miocene age was unlikely based on pollen data. Megirian et al. 2010 also used a late Oligocene age of 28-24Ma for the Namba Formation.
