Australia separated from Gondwana 99 Ma, and initially remained warm and humid with rainforest vegetation. Inland Australia had systems of rivers and lakes with abundant wildlife. Fossil birds, platypus, frogs and snakes are present from this period. From 30 Ma there was a period of global cooling, and from 15 Ma the Antarctic ice sheet formed.

Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues).
The site is located at the confluence of Dry Creek and the Maribyrnong River, 1.5 km (0.93 mi) north of Keilor, Victoria at The site was found when artefacts were exposed in sand quarries, and as a result of increased bank erosion of the river terraces due to runoff from the then recently opened Melbourne Airport.
The prehistory of Australia is the period between the first human habitation of the Australian continent and the colonisation of Australia in 1788, which marks the start of consistent written documentation of Australia. This period has been variously estimated, with most evidence suggesting that it goes back between 50,000 and 65,000 years.

The fossils at Riversleigh are unusual because they are found in soft freshwater limestone which has not been compacted.

The area is located within the catchment of the Gregory River. [3]
