An internationally significant fossil site in the Flinders Ranges, believed to contain the earliest evidence of sexual interaction, is now part of the Ediacara Conservation Park.

The Ediacara fossils found near Nilpena Station, about 500 kilometres north of Adelaide, are more than 500 million years old. They are some of the world’s oldest examples of multicellular, complex organisms, described by some as the “dawn of animal life”.
