Short summary
This study presents a paleobiological investigation and systematic taxonomy of early Cambrian calcified cyanobacteria in 10 shallow marine carbonate sections – both reefal and non-reefal – from South China. Our findings provide robust support for the view that cyanobacterial calcification was widespread in shallow marine environments and associated facies during the early Cambrian, defining a major cyanobacterial calcification episode (CCE).
This study presents a paleobiological investigation and systematic taxonomy of early Cambrian...
