Abstract in brief
The discovery of the oldest thylakoid membranes in fossilized cyanobacteria, dating back to about 178-173 billion years ago, provides direct evidence of oxygenic photosynthesis and helps narrow down when cyanobacteria diverged.
This finding extends the fossil record of cyanobacteria by at least 12 billion years and offers a minimum age of roughly 175 billion years for the split between thylakoid-bearing and thylakoidless cyanobacteria.
Analyzing the ultrastructure of these ancient fossils is crucial for understanding early Earth's oxygen levels, redox chemistry, and the evolution of complex life, making these fossils valuable for studying early biosphere changes.]

Cyanobacteria were one of the major actors in the Great Oxidation Event (GOE) around 2.4 billion years ago (Ga). A new study by Demoulin et al. determines the minimum age for the divergence of thylakoid-bearing cyanobacteria at roughly 1.75 Ga.
