Nimbadon is an extinct genus of marsupial, that lived from the Oligocene to the Miocene. Many fossils have been found in the Riversleigh World Heritage property in north-western Queensland. It is thought to have an arboreal lifestyle.
In 1990, skulls were unearthed in a previously unknown cave in the region. Researchers estimate that the first species of Nimbadon first appeared around 25 million years ago and went extinct around 12 million years ago, perhaps from climate change-induced habitat loss.
