We can’t know what Nimbadon looked like for sure, but the fossil record provides us some clues. It shows us that it was likely a curious-looking creature. Weighing in at a whopping 150 pounds, Nimbadon was about five times as large as a koala, a sloth-like figure with oversized claws, sizable hands and feet, and strong arms meant for clinging to the canopy.
The species was a type of diprotodontoids to which wombats and koalas are closely related. The similarities between koalas and Nimbadon are striking. They both depended on the forest, and they were both built to hang from the trees that they called home.
A prolific collection of fossils found in Queensland, Australia, paints a picture of a species shaped by a geology that no longer exists today on the continent.
