The fossil market has no shortage of STROMATOLITE fossils but in every case, they are modestly sized, 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 example of a MASSIVE stromatolite SUPER-COLONY of prehistoric cyanobacteria. Found as a single enormous piece, it shows a very rare instance of numerous spherically-shaped fossil cyanobacteria colonies growing on one another in the form of one gigantic super-colony of prehistoric bacteria. Giant single stromatolite fossil colonies in their natural form are very, very rare with few examples known like this specimen where they are portable. A fossil colony specimen like this is scarcer than words can describe, even more interesting it comes from the Permian Period. It is a lacustrine specimen so it was formed in prehistory in a freshwater ancient lake environment. On the sides are areas of drusy crystal formations in between some of the individual colony heads.
This showpiece specimen will most certainly provide for an unforgettable visual exhibit anywhere it is housed or shown. It is completely safe to touch so it would be a perfect. physical touch exhibit since the fossil is completely stable and durable.
This specimen 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. We invested countless hours in fine manual and pneumatic tool preparation to expose all the individual colony heads, revealing amazing globular detail rarely seen. 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.
This specimen dates to the Lower Permian Period. Permian fossils are intriguing because the end of the Permian Period marks the single most devastating mass extinction event ever on our planet. It is the Earth's most severe known extinction with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. The Permian Extinction is the only known mass extinction of insects. Some 57% of all families and 83% of all genera became extinct. Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after any other extinction event, possibly up to 10 million years.
