A UNESCO World Heritage Site and one of the best-known fossil sites in Australia. Fossils of different kinds of mammals, birds, reptiles, amphibians and fish have been found at the site - most notably 35 bat species. Unlike most fossils in the world, the ones found here have retained their original structure, as they are embedded in soft uncompressed limestone.
Riversleigh World Heritage Area is Australia's most famous fossil location, recognised for the series of well preserved fossils deposited from the Late Oligocene to more recent geological periods. The fossiliferous limestone system is located near the Gregory River in the north-west of Queensland, an environment that was once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The approximately 100 square kilometres (39 sq mi) area has fossil remains of ancient mammals, birds, and reptiles of the Oligocene and Miocene ages, many of which were discovered and are only known from the Riversleigh area; the species that have occurred there are known as the Riversleigh fauna.
One of the most unusual looking gorges in the park. Apart from Riversleigh, this gorge is one of the most important sights in Boodjamulla National Park. There's a camping area nearby for those wanting an early bird view.
