Australia's Vanished Beasts

Monodactyl Kangaroo
Sthenurus (genus)

In 1873, working only from fragments of skulls and jaws, the British comparative anatomist Sir Richard Owen named this genus of kangaroo Sthenurus, meaning "strong-tailed beast." Owen was prescient, for a century later when full skeletons were uncovered, this creature was revealed to have a tail stronger and shorter relative to body size than that of all living kangaroos. Its anatomy and teeth suggest it was a large, leaf-eating ‘roo that walked almost exclusively on its monodactyl ("one-toed") hind feet. The only survivor of its lineage may be the banded hare-wallaby, which survives on only two small islands off the coast of Western Australia.
