They were originally formed by the growth of layer upon layer of cyanobacteria, a single-celled photosynthesizing microbe that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils. Summary. Cyanobacteria are often the key organisms comprising microbial mats. They form dense micrometer-scale communities in which the full plethora of microbial metabolism can be present. Such mats are therefore excellent model systems and because of their analogy with Precambrian stromatolites they are also attractive subjects for evolutionary studies. Fossil cyanobacteria from the stromatolitic phosphorites of Udaipur, Rajasthan, West India M. S. Sisodia Department of Geology, University of Jodhpur, Jodhpur 342 001, India Small spherical bodies identified as fossil cyanobacteria have been found within or in the vicinity of stromatolites in the Precambrian Aravalii phosphorites of Udaipur. cyanobacteria are difficult to grow axenically.
