An 80-kilometre “dinosaur trackway” in the Kimberley region of Western Australia is a scientific treasure, unparalleled anywhere else in the world. The thousands of fossilised footprints were left by at least a dozen species of dinosaurs which lived 115 to 120 million years ago. They represent the largest number of footprints, the greatest diversity of dinosaur types and the best footprint preservation ever found, says Italian dinosaur expert Dr Giuseppe Leonardi. Dr Leonardi, from Naples, and Australian paleontologists Dr Tony Thulborn and Mr Tim Hamley of the University of Queensland, claim the footprints provide a unique opportunity to study the ecology and lifestyles of the long-gone animals.
The footprints range in size from micro-tracks a few centimetres long to mega-prints nearly a metre in length.
They reveal that the main groups of dinosaurs all roamed the region, which stretches north and south of Broome: theropods, sauropods, ankylosaurs, ornithopods and stegosaurs.
