Propleopus is an extinctgenus of marsupials. Three species are known: P. chillagoensis from the Plio-Pleistocene, and P. oscillans and P. wellingtonensis[3] from the Pleistocene. In contrast to most other kangaroos, and similar to their small extant relative, the musky rat-kangaroo, they were probably omnivorous.
