Mammoth tusk ivory comes from the two modified upper incisors of extant and extinct members of the order Proboscidea. Mammoths are believed to have been extinct for 10,000 years. Because of the geographical range in Alaska and Siberia, Mammuthus primigenius tusks have been well preserved. Therefore, Mammuthus primigenius is the only extinct proboscidan which consistently provides high quality, carvable ivory.
