Australonycteris is an extinct and monotypic genus of microchiropteran bat with the single species Australonycteris clarkae.[1] The species is known from fragmentary remains found at the Murgon fossil site, in south-eastern Queensland, dating to the early Eocene, 54.6 million years ago.[1] It is the oldest bat from the Southern Hemisphere and one of the oldest bats in the world,[1] and inhabited forests and swampy areas, with a diet of insects and probably even small fish.
Australonycteris, one of the oldest known bats, is known from several upper and lower teeth, an edentulous lower jaw fragment, a partial periotic bone, and several postcranial fragments. It has a forearm length of 40–45 millimetres (1.6–1.8 in), making it a medium-size bat, and it could echolocate. Australonycteris displayed some differences in dental anatomy, compared to extant bats, and it is possible that it foraged for insects and small fish.[2]
