Abstract
Many tetrads of coccoid cells were well preserved in the cherts of stromatolites from the Late Proterozoic Niyan Formation at Qingtongshan of Suxian, Anhui. Some of them exhibit tetrahedral tetrads, a feature similar to the tetrads of eukaryotic organisms, but they are actually of prokaryotic organisms. Their formation is the final outcome of cell shifting affected by diagenetic degradation and compaction.
