What potoroos are extinct?

The two extinct potoroos are the Gilbert's potoroo and the broad-faced potoroo. The Gilbert's potoroo was found only in Western Australia, and became extinct in the early 1900s due to habitat loss and predation by introduced predators. The broad-faced potoroo was found in Victoria, New South Wales and South Australia, and was also extinct by the early 1900s due to habitat loss, hunting and predation by introduced predators.
