Ancient Tethys Belemnite Split Nodule Own a piece of the "Roof of the World" that was once the floor of a prehistoric ocean. This rare Belemnite fossil, found in the sacred Kali Gandaki River valley of Nepal, offers a breathtaking look at marine life from the Jurassic Period ~150 million years ago. Known locally as "Thunderbolts," these fossils are the fossilized rostra (tail guards) of ancient squid-like cephalopods. This specimen is uniquely preserved within a natural concretion nodule, which has been expertly split to reveal the intricate beauty.
