Sculpted Stone

Here is a fantastic 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 ancient stromatolites were formed by masses of green or blue-green algae, or ''cyanobacteria''. This distinct plate of stromatolite displays many individual "cells" in textbook fashion. The cell structure is extremely well defined , and the unusual depositional pattern is wonderfully showcased. The natural coloration and the detailed mineral replacement is quite striking. This is an extremely collectible example of a rare stromatolite cluster from Australia.

A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
