Stromatolite is a remarkable fossil formed by layered sedimentary structures created by ancient cyanobacteria (blue-green algae). These fossils represent some of the earliest evidence of life on Earth, dating back billions of years, and provide valuable insight into the planet's early biological history.
Composed primarily of carbonate minerals or silica, stromatolites display distinctive layered patterns formed through the gradual accumulation of microbial mats and sediment. Their hardness varies depending on mineral composition, typically ranging from 3–7 on the Mohs scale.
Each specimen exhibits unique natural layering, color variations, and fossil structures, making every piece one of a kind and an excellent addition to fossil collections, educational displays, and geological exhibits.
