Koala with joey in a tree in South Australia. The koala's range covers roughly 1,000,000 km 2 (390,000 sq mi), and 30 ecoregions. [42] It ranges throughout mainland eastern and southeastern Australia, including the states of Queensland, New South Wales, Victoria, and South Australia. The koala was introduced to several nearby islands. [1]

Diprotodontia (/ d aɪ ˌ p r oʊ t ə ˈ d ɒ n t i ə /, from Greek "two forward teeth") is the largest extant order of marsupials, with about 155 species, [2] including the kangaroos, wallabies, possums, koala, wombats, and many others. Extinct diprotodonts include the hippopotamus-sized Diprotodon, and Thylacoleo, the so-called "marsupial ...
A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom.
The extinct species are presumed to have similar diet and habits to the modern koala, the largest Australian folivore, which was exceeded in size by the even more robust P. stirtoni. [11] The tail of koalas is almost absent, an unusual characteristic for a tree climbing mammal, although other anatomical features are well suited to that habitat.
A cladogram (from Greek clados "branch" and gramma "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be ...

Diprotodon is a marsupial in the order Diprotodontia, [d] suborder Vombatiformes (wombats and koalas), and infraorder Vombatomorphia (wombats and allies). It is unclear how different groups of vombatiformes are related to each other because the most-completely known members—living or extinct—are exceptionally derived (highly specialised forms that are quite different from their last common ...
