A stromatolite is a sedimentary fossil structure made by prehistoric bacteria colonies, typically cyanobacteria. Stromatolites in fact are still living and forming in some parts of our world today, including Australia, and are among the earliest forms of life—and fossils—on our Earth.

The fossils form in shallow water conditions of lakes or salt water shores. First, cyanobacteria grow in microbial mats. Minerals like calcium carbonate precipitate (crystalize from the water) onto the surface of the mat. The bacteria acts as a glue, cementing it all together with sedimentary debris. Layers build up over time like a bacterial pearl; the name “stromatolite” appropriately means “layered rock” in Greek.

This, however, is not a stromatolite. They are commonly believed to be stromatolites, and you will more often than not see them sold under that name and description. More accurately, they are concretions formed out of beautiful tones of red sandstone material. These sandstone concretions form in a manner similar to stromatolites, but minus the aid of bacteria: mineral-rich waters precipitate barite which binds with sand to form concentric layers around a nucleus. It is a relative of the barite desert rose, which grows clusters of round blade-like ‘petals.’

This shapely specimen makes for an inexpensive large piece to add to your mineral collection or use as decor around the home. I call this one the "Badonkadonk" because when flipped over, it appears as two pert semi-perfect spheres.

UV reactivity Many pseudo-stromatolites from Morocco have faint to moderate fluorescence and phosphorescence under 365 nm UV light. Some areas show brief phosphorescence, but overall reaction is poor.

Adorable but not sturdy :(
These are adorable and were perfect for a little dog wedding but... 3 days later and one has already come apart. My dog is not a big chewer so I was shocked to see it in pieces. She was able to detach the squeaker from inside. On a larger dog this would likely be a choking hazard. I've had several other toys from Zippy Paws and never seen this happen.

Cute set for small dog
My yorkie loves these! Super cute and the squeaker is good on all three which is what he loves. That way he can sit next to me and squeak them incessantly while I am on the phone and no other time. Perfect size for his little mouth. He doesn't tear up toys so I can't speak to durability.
