Proterozoic oceans are characterized by a thin veneer of oxygenated surface waters underlain by anoxic or euxinic deeper waters, and it has been hypothesized that metabolically flexible microbes such as cyanobacteria would have thrived under these co

Constraints on Precambrian ocean chemistry are dependent upon sediment geochemistry. However, diagenesis and metamorphism can destroy primary biosignatures, making it difficult to consider biology when interpreting geochemical data. Modern analogues
