Also known as Riversleigh

Where: Queensland, Australia (19.1° S, 138.7° E: paleocoordinates 34.0° S, 133.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Faunal Zone A zone, Carl Creek Limestone Formation, Chattian (28.1 - 23.0 Ma)

• Megirian et al. 2010: The oldest age estimate for an Etadunnan assemblage is derived from the magnetic polarity of Etadunna Formation faunal zone A at Lake Palankarinna, northern South Australia. This has been referred to magnetic polarity chrons 7An and 7Ar (Woodburne et al. 1994), which has an age of 25.3–24.9 Ma (Gradstein et al. 2005, Table 5.2). The Carl Creek Limestone produces distinctly Wipajirian and distinctly Camfieldian assemblages plus a suite of species that apparently ranged locally across the Wipajirian/Camfieldian boundary (Wipajirian–Camfieldian estimated to span ~24.9–12 Ma).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; carbonate
