Nope.  These are likely the Warrawoona stromatolites, which are dated to 3.5
Ga; these stromatolites are one of the oldest, if not the oldest, direct
evidences of life on Earth.  The oldest indirect evidence for life is the
banded iron deposits in Isua, Greenland, dated to 3.8 Ga.  I believe there's
also bundant Carbon 12 there, as well.
