The Riversleigh Rainforest Koala (Nimiokoala greystanesi) is an extinct species of marsupial, closely related to the modern Koala, that lived 10-16 million years ago in the middle Miocene of Queensland. It exhibits a similar diet as the modern species except for being only a third of its size, but the mouth protruded from the skull. Only a partial skull has been found to date along with other skeletal fragments.
