He flipped over a slab of ancient sandstone and saw something pressed into the stone: the faint, medallion-like impressions of soft-bodied creatures. He had no way of knowing it yet, but he was looking at some of the oldest evidence of complex life on Earth. These quiet hills, roughly 650 kilometres north of Adelaide, would give their name to an entire chapter of the planet's history: the Ediacaran Period, the first new geological period formally recognised in 120 years.
