Where: South Australia, Australia (28.8° S, 138.4° E: paleocoordinates 43.7° S, 133.7° E)

• coordinate stated in text

• small collection-level geographic resolution

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

• Beck et al. (2020): estimated to be 26-24 Ma old (i.e. latest Oligocene) on the basis of isotopic, foraminiferal, magnetostratigraphic and radiometric (Rb-Sr dating of illite) data. More recently, the Etadunna Formation has been proposed to be 26.1-23.6 Ma old based on a best-fit age-model of magnetostratigraphic data
