Riversleigh Fossil Site

Riversleigh Fossil Site, a UNESCO World Heritage site in remote northwestern Queensland, offers an extraordinary window into Australia's prehistoric past. This fossil-rich landscape, part of the Australian Fossil Mammal Sites, preserves remains from the Oligocene to the Miocene epochs, revealing ancient rainforests, bizarre megafauna, and early marsupials. For travelers fascinated by paleontology and raw outback landscapes, Riversleigh delivers a unique, mind-bending experience — though accessing it requires planning and a sense of adventure.

Highlights & What to See

• D Site (Dunnart Site): A prolific fossil deposit where you can see exposed bones of ancient mammals, including the carnivorous marsupial Wakaleo and the giant wombat-like Nimbadon. Interpretive signs explain the finds.
• Michelle’s Site: Famous for the stunningly preserved skull of a 15-million-year-old Thylacine (Tasmanian tiger relative) and other complete skeletons.
• Gag Site: Offers a glimpse into the aquatic past, with fossils of ancient crocodiles, turtles, and lungfish that once thrived in the region’s lush waterways.
• Riversleigh Fossil Centre (Outback at Isa): If you can’t make it to the remote site, this museum in Mount Isa (200 km away) houses an incredible collection of Riversleigh fossils, including the famous Thylacine skull and interactive displays.
• Self-guided walks: You can walk the limestone platforms at the main sites, but you’ll need a 4WD and a permit from the Queensland Parks and Wildlife Service to access the area.

Suggested Time to Spend

Dedicate at least a full day to visit the site itself, ideally as part of a longer outback road trip. The drive from Mount Isa (about 2.5 hours on unsealed roads) requires a sturdy 4WD and careful planning. Pair your visit with a half-day at the Riversleigh Fossil Centre in Mount Isa for context. Most travelers combine this with a few days exploring Lawn Hill National Park and the Boodjamulla (Lawn Hill) area, making a 3–5 day itinerary ideal for the region.
