The Chinchilla Local Fauna is one of the richest Pliocene vertebrate fossil assemblages in Australia. However, Vombatidae material preserved in the Chinchilla Sand is very poorly known, and no systematic examination of the wombats from Chinchilla has been conducted. Here I review the cranio-dental and mandibular wombat remains derived from Chinchilla. This material includes both adults and pouch-young specimens. At least five species of wombats are preserved in the fluviatile Chinchilla deposits, although a lack of stratigraphically controlled excavations makes it impossible to determine whether all five species were sympatric. Several wombat taxa are revised: Sedophascolomys gen. nov. is formally erected to replace the invalid ‘Phascolomys’; Vombatus mitchelli (Owen) is recognized as a species distinct from Vombatus ursinus (Shaw), and is recorded for the first time from Chinchilla. In addition to Vombatus mitchelli, the Chinchilla Sand also preserves evidence of Phascolonus gigas, Ramsayia magna, Ramsayia lemleyi and Sedophascolomys medius.
