Living Stromatolites, western Australia:
Stromatolite Fossils - Trezona Formation, South Australia, about 1 billion years old:
What's certain is that some stromatolite fossils look very old indeed, over 3 billion years.
So the question is whether those very oldest fossils are also stromatolites, or just some non-organic rock formation.

...
Exactly. Stromatolites are structures associated with mats of bacteria, but not the bacteria themselves. The oldest “fossils” have no remnants of bacteria in them so it’s a difficult question to answer.
Ten Misconceptions about the Geologic Column

The ten strata systems that geologists use (Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, and Tertiary) compose the “standard geologic column” and are claimed by many to contain the major proof of evolutionary theory. Several erroneous notions have been attached to the geologic column. The following are the ten most common misconceptions.
Misconception No. 1.
The geologic column was constructed by geologists who, because of the weight of the evidence that they had found, were convinced of the truth of uniformitarian theory and organic evolution.
