This paper will look at stromatolites in paleoenvironments and their importance, and the environments for which they are present in the Bahamas. I will be researching the paleoenvironments of stromatolites, examination of their abundance, and types of environments. Then look at stromatolites in their present environment in the Bahamas such as Exuma Cay, and Stocking Island.
