The fossil market has no shortage of STROMATOLITE fossils but in every case, they are sliced and polished slabs of a former fossil colony. The fossil colonies look little more than amorphous stone blobs prior to slicing, lacking any fine original life-like detail. This is an EXTREMELY RARE and unusual example of several LIFELIKE lacustrine (formed in a prehistoric lake) stromatolite colonies once deposited by prehistoric cyanobacteria. Most stromatolite collections lack Permian specimens and how many include actual three-dimensional examples of any period as this one shows? This specimen would make for an extremely scarce addition to the most advanced collection!
This fossil stromatolite multiple colony cluster has been laboriously prepared in our lab where we painstakingly removed the upper matrix rock layer to reveal all the delicate intact anatomy of each colony. The detail is so minute and intact that they appear as if still alive exactly similar to the living specimens found today in Shark Bay, Australia. We have never before seen such an exquisite fossilized cyanobacteria colony as these.
This specimen dates to the Lower Permian Period and contains a single, very thick unbroken block layer of matrix containing several small globular colonies. These colonies resemble spherical heads of cauliflower and the full inflation and realistic appearance of each specimen is truly amazing when you see them in person.
