27 March 2017: Unprecedented Dinosaur Track Diversity Along Western Australia’s “Jurassic Coast”

On 27 March, paleontologists from Australia’s University of Queensland and James Cook University announced that an unprecendented 21different types of dinosaur tracks had been identified along a 25 km (15.5 mile) section of the Dampier Peninsula on Australia’s western coast. Thought of as Australia’s “Jurassic Coast,” the diversity of tracks forms a primary record of non-avian dinosaurs for western Australia’s remote Kimberly region, between 127 and 140 million years old. Of the thousands of tracks in the area, 150 represent four main types of dinosaurs, including five different types of predatory dinosaur tracks, at least six types of tracks from long-necked herbivorous sauropods, four types of tracks from two-legged herbivorous ornithopods, and six types of tracks from armoured dinosaurs. These include the only confirmed evidence for stegosaurs in Australia and some of the largest dinosaur tracks ever recorded worldwide – sauropod tracks 1.7 m long. Since most of Australia’s other dinosaur fossils are on the eastern side of the continent, and between 115 and 90 million years old, the tracks in Broome are considerably older.”

Surrounding political issues had made the project intense – in 2008, the Western Australian Government selected the area as the preferred site for a $40 billion liquid natural gas processing precinct. However, after a political battle including the area’s traditional native Goolarabooloo people, the area was given an Australian National Heritage listing and the gas project collapsed in 2013.
