Both tusks were recovered from the same place in the Siberian permafrost in 2016. The left tusk weighs an impressive 6.2 kg and the right tusk 6.02 kg. The mammoth lineage branched from the Asian elephant around 6 million years ago, and later on the Woolly Mammoth, Mammuthus primigenius, evolved in eastern Siberia. Woolly mammoths, being slightly smaller than living African elephants, were foragers and ate grass, as well as small, nutritious flowering plants that flourished in the environment where they lived. They may also have used their curved tusks to dig through snow and eat plants that other foragers couldn't get to.
