Riversleigh World Heritage Area

Deep in the parched outback of north-west Queensland, Riversleigh is one of the world’s most important fossil sites – a haunting, ancient landscape that has yielded a jaw-dropping array of prehistoric mammals, birds and reptiles. This is not a polished museum experience; it’s a raw, open-air gallery of bones embedded in limestone, where you can stand where giant marsupials and carnivorous kangaroos once roamed. Part of the Australian Fossil Mammal Site (Riversleigh / Naracoorte) World Heritage listing, this remote site rewards intrepid travellers with a profound sense of deep time and the sheer weirdness of Australia’s evolutionary history.

Highlights & What to See

• D Site (Dunnart Site) – The most accessible fossil deposit, with a boardwalk and interpretive signs. Peer into the limestone to see skulls and jaws of ancient thylacines, marsupial lions and the bizarre Nimbadon, a tree-dwelling wombat-like creature.
• Site C (Gag Site) – A rich deposit named for the many jaws found here. Look for the remains of giant flightless birds, including the thunderbird Dromornis stirtoni, and early ancestors of today’s platypus.
• Site A (White Hunter Site) – The first major fossil site discovered here, yielding the skull of Ekaltadeta, a carnivorous rat-kangaroo, and the giant python Wonambi.
• Riversleigh Fossil Centre (Mount Isa) – If you can’t make it to the field, the excellent interpretive centre in Mount Isa showcases many of the best fossils and explains the science.
• Outback landscapes and wildlife – The drive to Riversleigh crosses vast spinifex plains and rocky gorges; keep an eye out for wallaroos, wedge-tailed eagles and, after rain, wildflowers.

Suggested Time to Spend

Allocate a full day to visit Riversleigh from Mount Isa (about 250 km, 3 hours one way), including 1–2 hours exploring the main fossil sites on the self-guided walk. For serious fossil enthusiasts, consider an overnight stay at the nearby Riversleigh Roadhouse or camp at Lawn Hill National Park (70 km north) to allow a more relaxed visit. The best time to visit is during the dry season (April to October) – summer heat and road closures can make access difficult.
