LARGEST MARSUPIAL


              The giant wombat Diprotodon was the largest
              marsupial that ever lived. Up to 10 ft (3 m)                                  About 10 ft (3 m) tall, the biggest
              long, it stood almost 7 ft (2.1 m) tall. It had                               species of Procoptodon was the
              enormous front teeth that it used to rip the                                  largest-known kangaroo; it lived
              leaves off bushes and trees, and big cheek                                    until about 50,000 years ago.

                 This enormous
                marsupial was a
              relative of the modern
             wombat and koala, and
              like them, it ate plants.

                                        similar to those of a wolf.

           Palorchestes; and the predatory marsupial lion       years ago, probably because climate change had
           Thylacoleo. During the ice ages, some of these       created a drier climate, but Thylacinus, also
           animals grew to huge sizes, like the giant kangaroo  known as the Tasmanian wolf, survived into
           Procoptodon and the hippopotamus-sized               the early 20th century.                              181
