Australia: The Land Where Time Began
A weathered fragment of bone, possibly from a dugong, has been found on the surface of a shell midden that had 5 lines of parallel incised zig-zags on it that were 1.5-2 mm deep along its length. The midden is undated but others from the area have been dated to the early to mid Holocene. It is thought it may be recent.
