 The
stromatolite is a light earth tone and exhibits fine banding throuout.
The formation from which it comes in Western Australia dates to
the Mesoproterozoic, to a time that with the first use of sex
on earth for reproduction and diversity was occuring, and when
the earliest cells with nuclei, the eucaryotes, were first appearing.
The
beautiful specimen has been polished to a mirror finish perpendicular
to the growth lines. Australian stromatolite is hard to get owing
to the remote localities.
