Ammonite Fossil Pair

The perfect mix of minerals and fossils! This beautiful 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 in half and polished to display the lovely 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. The Calcite crystals will even fluoresce under exposure to a UV flashlight! On the exterior of the shell, dendritic suture markings can be seen in some areas, along with rainbow iridescence. This fossil looks so beautiful from different angles and orientations, there is always a new display possibility to explore! Each Side of Pair Approx. 5" H x .5" Deep x 4.25" W
