Fossil ivory or mammoth ivory tusk is procured from the modified two upper incisors of the Woolly mammoth. This fossil ivory or Mastodon ivory is harvested from the fossilized remains of the wooly mammoths (Mammuthus primigenius) that have been extinct since the last 10,000 years. The remains of these huge animals are found in Siberia, Alaska and other regions of Russia. The fossilized ivory is a precious commodity which is extracted from the permafrost and thus, has high antique and historical value. The Mammoth ivory is as good as elephant ivory when it comes to its quality and luster.
