Lark Quarry Dinosaur Trackways

This joint initiative, implemented in April 2016, provides visitors with a broader understanding of unique Australian dinosaurs and the world they inhabited.

[citation needed] The Lark Quarry site is about 110 km (68 mi) south-west of the western Queensland town of Winton.

[4] The traditional account is that 104 to 92 million years ago, a group of perhaps 180 chicken-sized coelurosaurs and Bantam to emu-sized ornithopods were disturbed by the arrival of a single much larger theropod, perhaps Australovenator or a related form, which may have been up to 6 metres long with 50-centimetre feet.

With no significant difference in the form of the footprints, the authors attributed both Skartopus and Wintonopus were made by the same type of herbivorous bipedal dinosaur trackmakers.

Whatever actually took place, not long after the incident, the water level began to rise, covering the tracks with sandy sediments before the mud had dried.

Over thousands of millennia, the rich river plain with sandy channels, swamps and lush lowland forest dried up.
