Trace Fossils. The silence of Ediacara, the shadow of uranium.

This was a landscape of fossils and trace fossils - the preserved impressions
left by the passage of a living body through sediment - jostling for
attention. On this land surface, South Australia presents an arc extending
from the 'death mask' fossils of early multicellular life to the human leap into
the solar system. Sure, you might say, this could be said of many locations on
Earth. But here it seems laid bare for any wbo can read the distinctive pattern
of signs.
