WONDERS OF LAKE HAMLYN
Stromatolites are laminated structures built mainly by cyanobacteria
(sometimes
known as blue-green bacteria or, less correctly, as blue-
green algae). They are still found today, but were once much
more
common. They dominated the fossil record between about 2000 million
and 1000 million years ago. Nowadays they are
found mainly in saline
lakes or hot spring environments, often in environmental niches that
other organisms cannot tolerate.
The best example of living
stromatolites is at Hamelin Pool, Shark Bay, Western Australia.
