Diprotodon (meaning "two forward teeth") sometimes known as the "Giant Wombat" or the "Rhinoceros Wombat", was the largest known marsupial that ever lived. It was not an actual wombat. It was only distantly related to them.
It lived during the Pleistocene epoch of the Quaternary period, approximately from 1.6 million years ago until its extinction some 46,000 years ago.
The largest specimens of Diprotodon were hippopotamus-sized: about 3 metres (9.8 ft) from nose to tail, standing 2 metres (6.6 ft) tall at the shoulder and weighing up to 2,786 kilograms (6,140 lb). They inhabited open forest, woodlands, and grasslands, possibly staying close to water, and eating leaves, shrubs, and some grasses.
The closest surviving relatives of Diprotodon are the wombats and the koala.
