The Alcoota Kolopsis is a diprotodontoid marsupial that browsed on leaves and stems in the subtropical open woodlands. Its closest living relatives are the wombats and Koalas.

The Alcoota Kolopsis lived at a time in Australia when big, lumbering diprotodontoids outnumbered kangaroos in number of kinds and number of individuals.


Fossils of the Alcoota Kolopsis come from Alcoota Station in the Northern Territory. A complete skull has been found, as well as some individual teeth.
