The Willandra fossil trackway: Assessment of ground penetrating radar survey results and additional OSL dating at a unique Australian site

This paper presents some results of a ground penetrating radar survey conducted to establish the extent of the Willlandra Fossil Trackway, and further mapping of the footprints and intermingled tracks. In addition, it includes a refinement of the age range of the trackway, through further OSL dating, to between 19,000 and 20,000 years ago. Finally, it also provides a discussion of the geochemical composition of the trackway.
