Riversleigh, in North West Queensland, is one of Australia's most renowned fossil sites. The 100 km² area contains fossil remains of ancient mammals, birds and reptiles of Oligocene and Miocene age. The site was inscribed as a World Heritage site in 1994 and is an extension of the Lawn Hill National Park.
Fossils at Riversleigh are encased in limestone deposited by lime-rich freshwater pools, and in caves, at a time when the ecosystem was evolving from a rich rainforest to semi-arid grassland community. Thirty-five fossil bat species have been identified at the site, which is the richest in the world. The skull and nearly complete dentition of a fifteen million-year-old monotreme, Obdurodon dicksoni, provide a window into the evolution of this characteristically Australian group. Fossil ancestors of the recently extinct Thylacinus cynocephalus, the marsupial "Tasmanian Tiger", have also been identified among Riversleigh's fauna.
