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[1] and died out about 12 million years ago, perhaps from climate change-induced habitat loss.[2] Nimbadon lavarackorumNimbadon 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.[3]References1. ^1 Hand, S. J., et al.
