Woolly Mammoth Bone Bead Necklace String
Pleistocene Epoch, 2.6 million-11,700 years B.P.Estimate: £60 - 80 (+bp*)
Opening Bid: £5
Restrung, using recently polished oblate Mammuthus primigenius spherical bone beads. 135 grams, 58 cm
From a UK collection formed in the early 2000s. Property of an Essex, UK, gentleman.
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. -
