Stratigraphy

Formation:	Namba
Stratigraphy comments: 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.
