One of Jay’s coolest Mine Finds this month is the trilobite necklace! Trilobites crawled the earth over 500 million years ago, during the Cambrian Era. They were bottom dwelling marine creatures clad in a tough exoskeleton for protection. Most of the remains are actually outgrown (molten) exoskeletons that littered the ocean floor before succumbing to fossilization.
