Description:

Africa, late Cretaceous, ca. 145 to 66 million years ago; North America, Alaska, Pleistocene, ca. 100,000 to 10,000 years ago. A collection of fossilized ammonite shells and a fragment of fossilized mammoth ivory. The shells are both polished, one is cut in half to reveal the inner whorl patterning and vugs (cavities filled 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. Although fragmentary, the ivory shoes the telltale cross hatch graining along the splintered periphery. Size of cut ammonite: 3.25" Diameter x 1" W (8.3 cm x 2.5 cm)

This is an ESA antique exempt piece of fossilized mammoth ivory and cannot be sold internationally to several countries or to anyone residing in the states of California, Hawaii, Illinois, Nevada, New Hampshire, New Jersey, New York, Vermont, Oregon, and Washington DC. Please check your country’s laws before bidding on this piece.
