Mike's Menagerie Site (Miocene of Australia)

Also known as MM 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)

• The MM Site is listed among "System B"-aged sites in Travouillon et al. (2006, Alcheringia, 30, Suppl. 1, 323-349).

•The suboptimal stratigraphic nomenclature of Archer et al. (1997, Mém. Trav. École Prat. Hautes Études Inst. Montpellier, 21, 131–152) is replaced by a concept of faunal zones by Arena (2004, PhD thesis, Uviv. New South Wales, Sydney), confirmed by Travouillon et al. (2006). Faunal Zones A, B, C are identical to "Systems" A, B, C of Archer et al. (1997). Faunal Zone B is Early Miocene in age.

• 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 class: mesofossils

Collection methods: acetic,

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