That's right; stromatolites are fossils of very old bacterial colonies.
Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by bio-films of microorganisms, especially cyanobacteria (commonly known as blue-green algae). Stromatolites are a major constituent of the fossil record for about the first 3.5 billion years of life on earth and were responsible for creating the atmosphere we breathe.

What are the most common precambrian fossils called?
stromatolites
What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
The type of organisms that create stromatolites?
cyanobacteria
The earliest fossils known so far are fossilized mats of bacteria called what?
Stromatolites.
What era did simple organisms such as stromatolites live in marine ecosystems?
paleozoic ERA
What are the oldest fossils and what have they told us about the first organisms?
Some of the oldest known fossils are stromatolites, dating to 3.5 billion years ago. Stromatolites still exist today. They are round colonies of photosynthetic, single felled organisms without nuclei (prokaryotes).
What are the oldest fossils?
Stromatolites.
What fossils are from the Precambrian era?
Stromatolites
Name of the oldest fossil found in Australia?
The oldest fossils in Australia are 3.5 billion year old stromatolites. Stromatolites are layered accretions of prokaryotic microbes, most often made up of photosynthetic organisms. Stromatolites still live in Australia today.
