Fossil Shows Wombat Relative That Weighed More Than 300 Pounds – The New York Times

Koalas munch on eucalyptus, resemble living teddy bears and, like Australia s other imperiled native fauna, they need occasional rescuing. Wombats poop in cubes yes, cubes that they leave out and even stack to mark their territory. As for the animal itself, picture chonk incarnate, a burrowing ball of fuzz and fat powered by muscular little stub-legs.

Now multiply that five times. That s the size of a new long-lost member of the same animal group, Mukupirna nambensis, a mega-wombat that tipped the scales at well over 300 pounds. Scientists believe it scrounged around in the rainforest soil of Australia some 25 million years ago.
