One copper electroformed Ammonite Fossil complete on a 20" soldered copper chain. Ammonites lived during the periods of earth history known as the Jurassic and Cretaceous. Together, these represent a time interval of about 140 million years. Ammonites were marine animals that had a coiled external shell similar to that of the modern nautilus. Pendants measure approximately 1.5”. Size, shape, color and pattern may vary as no two fossils are alike.
