Mineral Specimens: Ammonite Fossils Small and Polished on One Side, each
Each fossil is half of an ammonite, flat and highly polished on the front, rounded and lightly polished on the back. Each ammonite is approximately 3/4 inch to 1.25 inches. Still a fossil so yours may have some rough spots. They stopped making these a few hundred million years ago so I can't return them to the manufacturer.
