I believe this item is a fossilized deciduous mammoth tusk. It measures 7" inches in length and approximately 1.25" in diameter (more or less). I purchased it from a small country auction. The auctioneer did not know what what it was and nobody else in the audience knew what it was so I got it for a very reasonable price. I wish I knew where this tusk was dug up at. The buyer pays .98 for US Mail Priority shipping. Thank you for your interest in this fossilized deciduous mammoth.
