Madakoala is a genus of extinctphascolarctidmarsupials with three known species, Madakoala devisi,Madakoala wellsiandMadakoala robustus. It is allied to extinct genera Invictokoala, Koobor, Litokoala, Nimiokoala, Perikoala, Phascolarctos and Priscakoala, along with Phascolarctos, the genus of the existing koala. Madakoala went extinct around 280,000 years ago in the Pleistocene epoch.[1] They are known to exist by limited cranial material in fossils, so the existence of some of the subspecies is questionable because of missing dental data.[2]
