Nimbadon is an extinct genus of Diprotodontia that lived in the Miocene epoch. 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 Nimbadon first appeared about 15 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.
