They are defined as laminated accretionary structures exhibiting synoptic relief.
They are defined as laminated accretionary structures exhibiting synoptic relief. The living members of this group tend to be found standing in hypersaline pools or other inhospitable locations, including a wetland reserve in the center of a Mexican desert. The earliest-known types thrived during the Archaean eon in dolostone- or limestone-rich areas. These microbial mats once coated entire ocean floors and tended to accumulate abiotic sediments, leading to their fossilization as the layered structures that give them their name, a Greek word that literally means "rock mattress." FTP, identify these formations of fossilized remains of cyanobacteria.
