Simosthenurus
''Simosthenurus,'' also referred to as the short-faced kangaroo, is an extinct genus of megafaunal macropods that existed in Australia, specifically Tasmania, during the Pleistocene. Through the radiocarbon dating of some ''Simosthenurus'' fossils, there was definitive evidence found that there are three lineages of macropods: Sthenurines, Macropodinae, and Lagostrophinae.〔 The ''Simosthenurus'' genus falls under Sthenurines.
The two most documented members of the genus are ''S. maddocki'' and ''S. occidentalis'', though other species have also been discovered.

Osteological information (predominantly cave floor surface finds) has yielded that ''Simosthenurus'' is part of the same family as that of modern kangaroos. However, modern kangaroos are plantigrade hoppers, using jumping as their means of locomotion, while ''Simosthenurus'' was a bipedal unguligrade, walking in a manner similar to that of hominids. Although members of ''Simosthenurus'' were no taller than most modern species of kangaroo, their robust bones, broad pelvis, long arms and short necks were unique adaptations to their browsing mode of feeding. They had single-toed hind feet had small hoof-like nails more typical of animals adapted to moving over relatively flat terrain.〔 ''Simosthenurus'' is highly distinct lineage of macropods, with no living descendants. However, it's possible that their closest living cousin is the banded hare-wallaby, which is now restricted to small isolated islands off the coast of Western Australia.
