Here is a beautiful specimen of a stromatolite. This is Baicalia capricornia from the Precambrian of Australia. This stromatolite is reported to be 1.2 billion years old! Authorities believe that stromatolites were formed by masses of green or blue-green algae, or ''cyanobacteria''. This distinct plate of stromatolite has been highly polished on one side for optimal display, and the layered depositional pattern is wonderfully showcased. The swirling, dark-green coloration of the mineral replacement is quite striking. This is a gorgeous columnar stromatolite from Western Australia.
