15-12 million years ago, mid Miocene.
Small herds of Nimbadon moved slowly through the forests, browsing on leaves and stems on the forest floor.
Nimbadon had large feet and claws, similar to those of today's Koala. It pulled in its claws when it walked.
Many perfectly preserved skulls of Nimbadon have been found at Riversleigh in north-western Queensland. Skeletons with the bones still articulated - that is, positioned as they would have been when the animal was alive - have also been found.

At least 24 Nimbadons were found within a few square m of each other at one site within the Riversleigh World Heritage property.
