There is only one extinct species in this family, the pig-footed bandicoot.

The pig-footed bandicoot was found in Australia. The last specimen was collected in 1901. It has probably been extinct since the 1950s.

The pig-footed bandicoot was a small marsupial with orange-brown fur, a long, pointed snout, a long, fur-covered tail, long, rabbit-like ears, and only two functioning toes on its front paws.

The female pig-footed bandicoot had a backwards-facing pouch.
