Australia's submerged heritage

In the first discovery of its kind, researchers have uncovered an ancient Aboriginal archaeological site preserved on the seabed. For most of the human history of Australia, sea levels were much lower than they are today, and there was extra dry land where people lived. Archaeologists could only speculate about how people used those now-submerged lands, and whether any traces remain today. But in a recent study published on PLOS ONE, we report the first submerged ancient Aboriginal archaeological sites found on the seabed, in waters of Western Australia (WA).
