Riversleigh World Heritage Area

Riversleigh World Heritage Area is Australia's most famous fossil location. The fossiliferous limestone system is located near the Gregory River in NW Queensland, an environment once a very wet rainforest that became more arid as the Gondwanan land masses separated and the Australian continent moved north. The 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.
