Wyoming Fossil Stromatolite is a remarkable fossil material from the Green River Formation in Wyoming. This ancient stone preserves colonizing bacteria, often of the species Chlorellopsis coloniata, which captured unique layers of geological history during formation. Over millions of years, this bacterial colony fossilized into lapidary-grade jasper. Each piece represents a tangible connection to ancient microbial life, making Wyoming Fossil Stromatolite both a functional lapidary material and a fascinating piece of Earth’s history.
WHAT MAKES IT SPECIAL
