Australia: The Land Where Time Began
A piece of trumpet shell (Syrinx aruanus), that is believed to have possibly been used as a water container, from this site has been dated to 18,510 +/- 260 years ago. The coast was about 130 km from the site at the time of occupation (Lorblanchet, 1992). The presence of the marine shell suggests the existence of long distance exchange/transport during the late Pleistocene.
