He also said that 'the small, medium and large tracks may have been made by three different species. They could also belong to two genders and a juvenile of one species, a little dinosaur family, but that’s purely speculative.' The 105 million year old tracks were discovered in sandstone rocks on the Milanesia Beach at the Great Otoway National Park, Victoria, Australia. Between 115 and 105 million years ago, Australia was joined to the Antarctic.
Dinosaurs thrived in the region. They were following their annual migration route when they passed over a summer floodplain after the glacial ice had melted. Apart from the tracks they left behind, the team also discovered preserved ripple marks and insect burrows, common features of floodplains. These particular tracks were made by three sizes of large theropod dinosaurs ranging from those of a chicken to a large crane.
