Pressed into the stone were the soft outlines of animals - frond-shaped, disc-shaped, segmented - and they were impossibly old. Reg Sprigg had stumbled onto the oldest known fossils of complex animal life on the planet, creatures that swayed and crept across a shallow seafloor some 550 million years ago, long before anything had a shell, a bone, or a backbone. Today the ground he was kneeling on sits inside Nilpena Ediacara National Park, a stretch of former cattle station in the northern Flinders Ranges that holds, by scientific consensus, the most complete fossil record of these animals anywhere on Earth.

In 2004, the International Union of Geological Sciences did exactly that, ratifying the Ediacaran Period - the first new period defined in roughly 120 years, and the first ever anchored in the southern ...

What makes Nilpena extraordinary is not single fossils but entire fossilised seafloors, lifted and turned over so that an ancient community can be studied as it lived. American palaeontologist Mary Droser has travelled here from California for more than two decades, working with ...

For generations this was Nilpena Station, grazing land worked by the Fargher family, who came to understand the treasure beneath their paddocks and quietly protected it. In 2019 the South Australian government bought a large portion of the station, enlarging the protected area ro...
