Ah.. Another update needed on my timescale project.

Apparently it is eukaryotic photosynthesis that started then. I've seen other references that mention evidence for photosynthesis much earlier than that (prokaryotic? - stromatolites, etc.)

 

Again, I've yet to see pics of those fossils! Heard of Bangiomorpha but never seen them.
