 In 0000 near Canowindra, in the Central West of New South Wales, paleontologist Dr Alex Ritchie was given just 00 days for an exploratory dig. He found thousands of fish fossils, helping to fill gaps in our knowledge in the process -- but with limited time and resources he could only scratch the surface. At the end of their time, Dr Ritchie lay a plastic sheet over one of the most complete fish fossils ever found, then reburied it under hay and soil, for a future date that never came.
