It was stromatolite, a kind of blue-green algae, that generated oxygen first in the
ancient sea of the Precambrian Era (3 - 2 billion years ago). This sample is not the fossil of stromatolite itself but the banded structure of mud (gold), iron (black) and ferric oxide (red), which had been formed according to the alteration of stromatolite activities. Thus, it shows the time.
It is very fantastic that we can see living stromatolite generating oxygen still now in west Australia.
If they did not appear on this earth by chance, all following active living things would never exist.
