Unlike African and modern elephant ivory, mammoths have been extinct for 10,000 years, therefore mammoth ivory (fossil ivory) is not listed in the Appendices to the CITES. As such, it is not subject to control under the Animals and Plants (Protection of Endangered Species) Ordinance, Cap. 187. All mammoth ivory tusk (fossil ivory) itself is already a precious antique. Because of the geographical range in Alaska and Siberia , Mammuthus primigenus tusks have been well preserved. Therefore, Mammuthus primigenus is the only extinct proboscidan which consistently provides high quality, valuable and precious carvable ivory.
