Woolly Mammoth Fossil Tusk
Pleistocene Period, circa 40,000 B.P.Sold for (Inc. bp): £1,690
From Mammuthus primigenius, professionally conserved and polished to a high standard. 620 grams, 40.5 cm
Acquired on the UK art market. From the private collection of an East Anglian, UK, specialist collector.
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 were unable to reach. -
