'''''Nimbadon''''' is an [[extinction|extinct]] [[genus]] of marsupial, that lived from the [[Oligocene]] to the [[Miocene]].<ref name="Hand1993" /> Many [[Fossil|fossils]] have been found in the [[Australian Fossil Mammal Sites (Riversleigh)|Riversleigh World Heritage property]] in north-western [[Queensland]]. It is thought to have an [[Arboreal locomotion|arboreal]] lifestyle.<ref name=":0">{{Cite journal |last1=Black |first1=Karen H. |last2=Camens |first2=Aaron B. |last3=Archer |first3=Michael |last4=Hand |first4=Suzanne J. |date=2012-11-21 |editor-last=Evans |editor-first=Alistair Robert |title=Herds Overhead: Nimbadon lavarackorum (Diprotodontidae), Heavyweight Marsupial Herbivores in the Miocene Forests of Australia |journal=PLOS ONE |language=en |volume=7 |issue=11 |pages=e48213 |doi=10.1371/journal.pone.0048213 |issn=1932-6203 |pmc=3504027 |pmid=23185250 |bibcode=2012PLoSO...748213B |doi-access=free }}</ref>

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<ref name="Hand1993" /> and went extinct around 12 million years ago, perhaps from climate change-induced habitat loss.

== Description ==
''Nimbadon lavarackorum'' is described as being [[koala|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.<ref>[http://www.abc.net.au/science/articles/2012/11/22/3637755.htm Ancient tree-wombat behaved like a koala] - By Anna Salleh - Australian Broadcasting Corporation - Retrieved 22 November 2012.</ref>

== Phylogeny ==
While originally classified as a member of the family [[Diprotodontidae]], a primarily terrestrial group,<ref name="Hand1993" /><ref name=":0" /> some later studies suggested a more basal position within the [[Diprotodontoidea]].<ref>{{Cite journal |last1=Beck |first1=Robin M.

== Palaeoecology ==
''N. lavarackorum'' was an arboreal [[frugivore]] that primarily fed on [[C3 photosynthesis|C<sub>3</sub>]] fruits.<ref>{{Cite journal |last=DeSantis |first=Larisa R.
