Riversleigh

Riversleigh is one of Australia 's most renowned fossil sites. The process by which these fossils were created included large Sand Dune s that once covered this area. These sand dunes contained large traces of Calcium as well as Limestone that were laid down by the ancient sea. Fossils of '' Diprotodon optatum'' have only been found here once and are thought to have originated from as far west as modern Darwin, Northern Territory and brought to this site by the slow moving sand dunes due to the overall gradient of Australia at that period of time due to the ancient sea having flooded this section of Australia 500 million years ago.

Fossils have been found here and are thought to be a result of protection of millions of years from the sand dunes which inturn cause the burial of these fossils in calcium and limestone compressed over this period of time.
