Ammonite #2(1145) Placenticeras costatum. Measures approximately 38 cm. (15″) in diameter. This ammonite displays great shape, as well as excellent colours on both sides. They range from reds, oranges, golds, greens and quite a lot of the rare blues. There are also visible bitemarks, thought to be from a marine reptile, that is most likely from a mosasaur. This ammonite comes from the top of the Bearpaw formation at the Korite mine. Only in one small area of North America does one find this brilliant gemstone. Over millions of years, the nacre of the ammonite’s shell has been transformed to take on this wild range of iridescent colouring. It comes with a wood display stand and a certificate of authenticity. For international shipping, all customs paperwork is included. This specimen is registered with the Government of Canada and leaves the country with all the required permits and documentation.
