Riversleigh, in North West Queensland, is Australia's most famous fossil site. The 100 kmē area has 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 found in limestone by lime-rich freshwater pools, and in caves, when the ecosystem was evolving from 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.
