Ammonite

Ammonite shells joined together during sedimentation processes and later skilfully prepared from the surrounding rock. The ammonite stands out for its very well-preserved nacreous layer, which retains its iridescent lustre even after millions of years. The ammonite group measures 9 × 7.5 × 5 cm. The base of the stand measures 5 × 5 cm, the height is 3 cm.
