Indonesian Stone Fossilized Shell

Dark streaks and a white core give this spiral a faintly stormy look.

This fossilized shell from Sulawesi is from Sulawesi, Indonesia. It is stone. Sulawesi is a large island in Indonesia with a complex geology, and marine sediments there contain the remains of shells and other sea life. Overall, a smooth coil with a pale, bright inner ring and darker grey patches on its outer turns. One side has a jagged broken edge that exposes a rough interior, and the center ends in a tiny curl. It is 5 inches wide, 5 deep and 6 high.

Cracked at one corner but spiraling along bravely.
