Sthenurinae (from Sthenurus, Latin for 'strong-tailed') is an subfamily within the marsupial family Macropodidae, known as 'short faced kangaroos'. No members of this subfamily remain extant today, with all becoming extinct by the late Pleistocene. Procoptodon goliah, the largest macropodid known to have existed, was a sthenurine kangaroo, however sthenurines come in a range of sizes, with Procoptodon gilli being the smallest at the size of a small wallaby.
