East Africa, Madagascar, Jurassic to Cretaceous period, ca. 200 to 66 million years ago. A pretty ammonite fossil hat has been cut and polished to reveal the natural and fascinating interior whorl patterns and vugs (cavities lined with crystals). The material inside the chambers turned into quartzite stone when water with silica and other minerals in the ocean sediment seeped in, permeating the organic material, and later solidifying in some chambers and forming textured crystalline structures lining the surfaces of others- which are known as druzy vugs! Size: 3" Diameter x 0.5" W (7.6 cm x 1.3 cm)
