Diprotodontian
Diprotodontia (, from Greek language, Greek "two forward teeth") is the largest extant order (biology), order of marsupials, with about 155 species, including the kangaroos, Wallaby, wallabies, Phalangeriformes, possums, koala, wombats, and many others. Extinct diprotodonts include the hippopotamus-sized ''Diprotodon'', and ''Thylacoleo'', the so-called "marsupial lion". Characteristics Living diprotodonts are almost all herbivores, as were most of those that are now extinct. A few insectivore, insectivorous and omnivore, omnivorous diprotodonts are known, and the Potoroidae are almost unique among vertebrates in being largely Fungivore, fungivorous, but these seem to have arisen as relatively recent adaptations from the mainstream herbivorous lifestyle. The extinct Thylacoleonidae, thylacoleonids ("marsupial lions") are the only known group to have exhibited Carnivore, carnivory on a large scale. Diprotodonts are restricted to Australasia. The earliest known fossils date to th ...

Diprotodon
''Diprotodon'' (Ancient Greek: "two protruding front teeth") is an extinct genus of marsupial from the Pleistocene of Australia containing one species, ''D. optatum''. The earliest finds date to 1.77 million to 780,000 years ago but most specimens are dated to after 110,000 years ago. Its remains were first unearthed in 1830 in Wellington Caves, New South Wales, and contemporaneous paleontologists guessed they belonged to rhinos, elephants, hippos or dugongs. ''Diprotodon'' was formally described by English naturalist Richard Owen in 1838, and was the first named Australian fossil mammal, and led Owen to become the foremost authority of his time on other marsupials and Australian megafauna, which were enigmatic to European science. ''Diprotodon'' is the largest-known marsupial to have ever lived; it greatly exceeds the size of its closest living relatives wombats and koalas. It is a member of the extinct family Diprotodontidae, which includes other large quadrupedal herbivor ...
