Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
Biofilms of microorganisms, especially cyanobacteria, are found on the outter surfaces of stromatolites.
Proterozoic is called the "Age of Stromatolites" (Abundant in Proterozoic shallow seas)
