The Mygoora Local Fauna (new name) from Mygoora Lake, central Australia (southern Northern Territory), consists of the fossilised remains of 12 vertebrate species referrable to modern taxa. The assemblage includes eight marsupials (Bellongia lesuew; Dasycercus cristicauda, Dasyurus geo.ffroii, Lagorchestes hirsutus, Lasiorhinus cf. latifrons, Macropus rufus, Macrotis lagotis, and Sarcophilus harrisii), two rodents (Notomys alexis and Ralltts villosissimus), and two reptiles (Varanus sp. and a pythonid, ?Bothrochilus sp.). Lasiorhinus sp. (hairy-nosed wombat) is a first record of the genus in the Northern Territory, while Sarcophilus harrisii (Tasmanian devil) is a first record for central Australia, both records representing extensions of prehistoric ranges for these species. Four species (Bettongia Iesueur, Dasyurus geo.ffroii, Lagorchestes ltirsutus and Macro/us lagotis) became regionally extinct in historical times. The fauna is dominated by fossorial species, or species known to occupy existing burrows, that are typical of the Australian arid biogeographic zone. Articulated skeletal remains were preserved in burrows dug into stabilised aeolian sand, with subsequent deflation resulting in localised concentrations of durable fragments at the present land surface. An optically stimulated luminescence (OSL) date of the host aeolian sand provides a maximum age of between 12.1 +/-0.5 and 9.3+/-0.6 ka for the assemblage. A minimum age could not be determined, but biochronological data suggest that the fauna is possibly of latest Pleistocene or early Holocene age.
