Riversleigh in the north-west of Queensland is Australia’s most famous fossil site. The 100 km² area has fossil remains of ancient mammals birds and reptiles of Oligocene and Miocene age.The fossils at Riversleigh are rare because they are found in soft freshwater limestone which hasn’t been compressed. This means the animal remains retain their three-dimensional structure. The area is located within the catchment of the Gregory River.Fossils were first noted to exist in the area in 1901.
