Columnar stromatolites from intertidal zone of Hamelin
Pool, Shark Bay, Aus.
(Awramik, 1984) |
The environments for stromatolites are very
wide ranging. They are not only able to live in intertidal and supratidal
environments but also in deep water environments

They can survive exposure during low tide, therefore
they are resistent to dessication, high temperature and solar radiation.
Cyanobacteria can range to depths of 100m because of their
photosynthetic capabilities.
