About Petrogale assimilis Ramsay, 1877
The allied rock-wallaby, Petrogale assimilis, has few physical features that distinguish it from its close relatives, though each related species occupies a distinct geographic range across Queensland and northern New South Wales. Where their ranges slightly overlap, some hybridisation occurs. All of these related wallabies have upper body fur ranging from brown to grey, with paler fur on the underparts. The allied rock-wallaby typically has a dark muzzle and a dark patch around its armpits, plus a pale stripe on its cheek and a second pale stripe across its hips. This species is endemic to Queensland, Australia. Its distribution extends from Townsville to the Burdekin River, Bowen River, Croydon, and Hughenden, and it is also found on Magnetic Island and Palm Island. It occurs in rocky habitats at elevations up to 1,000 m (3,300 ft), inhabiting both woodland and more lightly treed areas, even when these areas are located adjacent to agricultural land. Its typical habitat consists of mountainous terrain containing cliffs, ledges, caves, and rock piles.
