STROMATOLITE from Minnesota


STROMATOLITE from Minnesota. 30 lbs Mary Ellen Jasper 1.88 billion years old

SKU: ST003 Category:


Stromatolites are layered sedimentary formations (microbialite) that are created mainly by photosynthetic microorganisms such as cyanobacteriasulfate-reducing bacteria, and Pseudomonadota (formerly proteobacteria). These microorganisms produce adhesive compounds that cement sand and other rocky materials to form mineral “microbial mats“. In turn, these mats build up layer by layer, growing gradually over time. A stromatolite may grow to a meter or more.  Although they are rare today, fossilized stromatolites provide records of ancient life on Earth.
