A beautiful pair of polished Ammonite halves. Boxed set.
Fossil Ammonites are cut through the centre and each of the halves is polished. To ensure they are a matching pair the polished halves are taped together until packed. Sometimes you can see the mark of the tape on the back of the fossil.
Each pair is unique. Occasionally the buoyancy cavities, which the animal used to rise and descend through the water, are filled with crystals. Sometimes the back of the fossil shows evidence of opalescence.
