    Woolly Mammoth Bone Bead Necklace String

    Estimate: £60 - 80 (+bp*)

    Bids: 1   |   Current Bid: £5

    Restrung, using recently polished Mammuthus primigenius spherical bone beads. 155 grams, 58 cm



    Ex Ancient Art Shop, Windsor, UK, 1990s. Ex private West County, UK, collection.

    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.

    The Mosasaur is an extinct, large marine reptile dinosaur with an elongated body, long snout and paddle-like limbs. Found worldwide, they competed with other well-known sea predators of the Late Cretaceous, such as plesiosaurs and ichthyosaurs, for food, existing primarily on a diet of ammonoids, cuttlefish and fish.
