Fossilized Shell This specimen is a fossilized brachiopod from the Devonian period- about 400-450 million years ago. It was found near the Cedar River in central Iowa. When this little guy was alive Iowa was a shallow ocean filled with coral reefs and thriving marine life. I have been finding a ton of fossils and have over 100 I will be posting. Follow if you are interested! Kept in a smoke-free home. #fossil #crystal #geology #nature #rocks
