Title

Stromatolites at Shark Bay Western Australia #47650172

Description

Stromatolites are rock-like structures built by microbes (single-celled cyanobacteria, also known as blue-green algae). Shark BayÃ¢â¬â¢s stromatolites are only 2,000 to 3,000 years old, but they are similar to life forms found on Earth up to 3.5 billion years ago. They provide a unique insight into what the world was like at the dawn of time.
