Ammonite

• Ammonite
  [Is an ammonite god’s horn?]
  
  Ammon, the god of industry of the ancient Egypt, had curled horns of the ram on his head.
  Mysterious stones like curled seashells had begun to be called “ammonite” as meaning “Ammon’s horn”.
  These are some of many various-shaped ammonites in our museum.
