† Nimbadon

SPECIES SCORED: † Nimbadon lavarackorum (type and only described species).

GEOLOGICAL PROVENANCE OF SCORED SPECIMENS: AL90 Site (Riversleigh Faunal Zone C), Riversleigh World Heritage Area, Queensland, Australia.

AGE OF SCORED SPECIMENS: The AL90 Site is considered to be part of Riversleigh Faunal Zone C, which is interpreted to be middle Miocene based on biostratigraphy (see above). Radiometric dates for the AL90 Site span 14.17–15.11 Mya.

ASSIGNED AGE RANGE: 15.110 –14.170 Mya.

REMARKS: † Nimbadon lavarackorum is represented by a remarkable series of well-preserved individuals from the AL90 Site at Riversleigh, which have been used for scoring purposes here, plus additional less-well-preserved specimens from other Riversleigh Faunal Zone C sites that were not scored (Hand et al., 1993; Black, 2008; Black et al., 2010; Black and Hand, 2010). The AL 90 specimens range in ontogenetic stage from pouch young to old adults, represent both putative males and females, and include multiple intact skulls (Hand et al., 1993; Black, 2008; Black et al., 2010; Black and Hand, 2010). † Nimbadon is currently placed within the diprotodontid subfamily †Zygomaturinae based largely on P3 morphology (Hand et al., 1993; Murray et al., 2000b; Black, 2008; Black et al., 2010; Black and Hand, 2010).
