Large Ammonite Fossil Pair

A fossil with crystals inside! This large split Ammonite pair comes from Madagascar. Ammonites are an extinct group of sea creatures. This Ammonite, a Cleoniceras, was thriving during the Cretaceous Period approximately 110 million years ago. The Ammonite shells are cut or split in half and polished to display the beautiful mineralization which has occurred within their growth chambers. With this particular specimen, Calcite began to infill the once hollow growth chambers. Some chambers completely filled with Calcite, while others still exhibit individual Calcite crystal pockets. Incredible dendritic suture markings can be seen on the exterior of the shell as well. This fossil looks so beautiful from different angles and orientations, there is always a new display possibility to explore. They even fluoresce when exposed to a UV flashlight!

Each Side of Pair Approx. 7" H x 1" Deep x 5.5" W
