Ammonite pair of 14 cm

Ammonite is about 112 million years old and completely fossilized. This piece is cut and polished. This makes the different rooms nicely visible. The two halves  form a pair together and give a good idea of how the ammonite slowly grew, by expending with one room at a time.  This ammonite weighs 805 grams

Fossil ammonite from Madagascar

The most beautiful ammonites are found in Madagascar and may have dimensions up to 25 cm in diameter. This ammonite belongs to the Cleoniceras family. In some hollow chambers grew calcite crystals. These are actually crystal geodes inside the fossil. Ammonites became extinct about 65 million years ago, just like the dinosaurs.
