Here is a beautiful specimen of a fossilized stromatolite. This is Acaciella australica from the Precambrian of Australia. This stromatolite is reported to be over 1 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 unusual depositional pattern is wonderfully showcased. The natural coloration and the detailed mineral replacement is quite striking. This is a fabulous example of a rare stromatolite from Australia.
