2012 $1 Kangaroo Mareeba Rock Wallaby 1oz Silver Proof Coin

Identifying a Mareeba rock-wallaby can be difficult without the help of a microscope. Mareeba rock-wallabies are almost indistinguishable from several other Petrogale species, including Sharman's rock-wallaby and the Allied rock-wallaby. These endearing Australians all have well-adapted feet for hopping over rocky terrain and long, flexible tails. Their most significant distinction is the distribution, shape and number of their chromosomes. It wasn’t until 1992 that the Mareeba rock wallaby, named after an area in Queensland, where it is found, was declared a separate species.
