Nimbadon is an extinct genus of the family Ilariidae, from the suborder Vombatiformes, and order Diprotodontia that lived from the Late Oligocene to the Miocene epoches. Many fossils have been found in the Riversleigh World Heritage property in north-western Queensland.
In 1990, skulls were unearthed in a previously unknown cave in the region. Researchers estimate that the first species of Nimbadon first appeared about 25 million years ago and died out about 12 million years ago, perhaps from climate change-induced habitat loss.
Nimbadon lavarackorum is described as being koala-like. It is known from as many as 24 well-articulated specimens. The species was a tree-dweller, mainly feeding on stems and leaves. The feet and claws were large, being superficially similar to those of the koala. They retracted their claws when walking.
