A polished section slice of a tooth of the extinct Woolly Mammoth (Mammuthus Primigenius); the slice showing the original biting surface to the upper face, and datting Circa 30,000 BC. The section measures approx 6.5" x 3" maximum (approx 16.5cm x 7.7cm) Condition is fine, and would make an excellent display specimen.

Fishing trawlers occasionally bring up bones and relics from when the area was inhabited as dry land. Shipping : UK £4.00 Europe £5.00 US /Can/RoW £6.50   « Less
