Riversleigh (Riversleigh Fossil Site), located south of (Boodjamulla National Park), Porter Gamra National Park, is a fossil site covering an area of about 100 square kilometers, scattered with a variety of ancient mammals and birds. Riversleigh was inscribed on the World Natural Heritage list by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1994 (the fossil remains of Australian mammals, together with the Naracoorte Caves National Park of the Naracut Cave National Park in South Australia).
Riversleigh's fossil population is also one of the richest and most extensive in the world, some dating back to 1500 to 25 million years ago, and the fossil species, in addition to the animals that still exist today, such as kangaroos, kangangmole and pinnacle opossum, It also includes many extinct species, such as bag lions. The discovery of fossil animals in Australia, the world's most isolated and unique continent, provides a scientific basis for scientists to study the evolutionary history of marsupials that are unique to the land.
Riversleigh is open to the public, where visitors can see many fossils of mammals and reptiles.
