Here is a very distinct Conophyton Stromatolite specimen from the Lower Ordovician of Wisconsin. Authorities believe that stromatolites were formed by masses of green or blue-green algae, or ''cyanobacteria''. This particular stromatolite has been dated to 500 million years old! This large slab has been highly polished on one side for optimal display. The colorful, layered mineral replacement is clearly defined and makes for a unique presentation. This is a beautiful example of this extremely unusual stromatolite from the Midwest.
