During the Cretaceous Period, much of Outback Queensland was part of an extensive Inland Sea. Take a journey through time and discover why the ocean filled the Outback; how approaching the Tropic of Capricorn changed Boulia forever; and how the Great Artesian Basin you stand in today links us to this dramatic past. The Stone House Museum in Boulia features an extensive vertebrate and invertebrate fossil display. See the remains of large fossil marine reptiles, sharks, and fish that once inhabited this region. The museum's unique stone design keeps out the harsh summer heat, typical of the Tropic of Capricorn. Take a guided tour with local expert 'Dinosaur Dick' Stone House Museum's Marine Dinosaur Collection. Before departing Boulia, decide for yourself whether the Min Min light is a geological wonder or supernatural phenomenon at the spine tingling Min Min Encounter. Heading West West of here waits the stunning panoramas of the Northern Territory. Heading East Heading east see the dinosaur trackways at Lark Quarry. Around 95 million years old, this is the only recorded dinosaur stampede on earth. Your geo adventure continues at Winton's incredible Australian Age of Dinosaurs Museum, as you enter the fascinating world of paleontology.
