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.

Beautiful but…
Size: 48in, Color: 3tier
I have bought a half dozen of these shelves over the years and installed them in my own home and family members homes. They are beautiful once they are up. The quality of the pipe and wood are great, heavy duty. BUT Somehow I seem to forget that the installation is a complete nightmare-borderline not worth it. The pipe never likes to line up properly and when it does it’s just not tight leaving the whole thing feeling wobbly. Once installed it is very beautiful and sturdy. The other part I also seem to forget is that the anchors are complete and utter crap! Save yourself the frustration and TOSS THEM immediately. Its a huge waste of time attempting to use them and your so pissed off by the time you realize it that you almost don’t even want the shelf anymore😂 In summary- Beautiful, quality shelf but buy your own anchors and round up you patience prior to install.

I like to have a three-dimensional wall shelf at home. I can display plants, photos and other items well. It is great. I haven't taken care of it yet. I need to put more beautiful items. Oh, by the way, it is of good quality. It is a little heavy. The merchant provides expansion screws for hanging it on the wall. It is also very simple to assemble... I am very satisfied with the effect and I like it very much.

Great Accent Piece
Size: 48in, Color: 3tier
Industrial looking with wide shelf space. We were looking for a functional accent piece that we can also put things on. This new addition has been more than perfect. It provides a rustic feel and it has the industrial bars that holds the shelves which is the best. Very sturdy, please make sure to assemble on studs this piece is heavy. It looks really good in our living area.
