Riversleigh fossil trail
Delve into Australia's prehistoric past and discover many kinds of ancient fossils at this intriguing World Heritage site.
At Riversleigh, near Miyumba camping area, follow this steep but fascinating trail through an ancient landscape to the top of a limestone outcrop.
Along the way, step back in time as you spot fossils of extinct animals—the gizzard stones of a towering flightless bird, ‘Big Bird’, and the remains of ‘Baru’, the largest known freshwater crocodile.
This site is part of one of the most significant fossil deposits in the world. Experience a tantalising glimpse of the rich record of life following the separation of Australia from the early continent of Gondwana.
Visit in the early morning or late afternoon as it can be very hot during the middle of the day.
The Riversleigh fossil trail is part of the Australian Fossil Mammal Sites (Riversleigh/Naracoorte) World Heritage Area, famed for its outstanding examples of the record of life and evolutionary history.
