Riversleigh Sprite Possum
23-10 million years ago, early - middle Miocene.
The Riversleigh Sprite Possum belongs to an extinct group of possums called the ektopodontids. It had a short face, huge, forward-facing eyes, and unusual teeth that it probably used to eat seeds or hard fruits in the forest.
The closest living relatives of the Riversleigh Sprite Possum are the brushtailed possums and cuscuses.
The only fossils known for the Riversleigh Sprite Possum are a lower jaw and some individual teeth, from Riversleigh in north-western Queensland.
