Abstract Natural casts of seven small footprints have been identified on a single weathered block derived from the Precipice Sandstone (Lower Jurassic) of the Carnarvon Gorge, southeastern Queensland. The footprints are attributed to omithopod dinosaurs and are referred to the ichnogenus Anomoepus. They appear to be most similar to the ichnospecies Anomoepus gracillimus, originally defined on footprints from the Lower Jurassic of the northeastern United States. This identification is consistent with the presumed age of the Precipice Sandstone, since Anomoepus or closely related ichnotaxa are common in Leaver Jurassic sediments of the United States, Europe and southern Africa but have never been identified with certainty in Triasac sediments. The tracks described here were made by at least four dinosaurs, all estimated to have been about 30 cm high at the hip and less than 1 -3 m in total length. In their general appearance these animals probably resembled the small plant-eating dinosaur Fabrosaurus (Lesothosaurus), from the Lower Jurassic of southern Africa. Tracks of two animals provide estimates of walking speeds between 0.68 and 0.80 m/s (2.4 and 2.9 km/h). These footprints are the earliest evidence for the existence of omithischian dinosaurs in Australia.
