Inabeyance Site (Miocene of Australia)

Also known as Inabeyance Site, Riversleigh

Where: Queensland, Australia (19.1° S, 138.7° E: paleocoordinates 30.8° S, 134.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Faunal Zone B zone, Early/Lower Miocene (23.0 - 16.0 Ma)

• All the Riversleigh site LFs are interpreted to be part of Riversleigh’s Faunal Zone B as distinguished by Archer et al. (1989, 1997), Arena (2004) and Travouillon et al. (2006, 2011), except Cadbury's Kingdom LF which is thought to be part of Faunal Zone C, but see discussion below. They are inter- preted to be early Miocene in age on the basis of biocorrelation of their contained faunas (Travouillon et al., 2006, 2011). (Travouillon et al. 2014)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; carbonate

• Fossiliferous rocks of the Riversleigh area are said to represent freshwater carbonates whose depositional history appears to involve a complex sequence of fluvial and karst processes (Archer et al., 2006, Alcheringia, 30, Suppl. 1, 1-17 and references cited therein).

Size classes: macrofossils, mesofossils

Collection methods: acetic,

• "Riversleigh fossils are rarely articulated but usually undistorted, can be completely freed from matrix with acid [...]." (Scanlon, 2006).
