This is about 15,000 years old! this is just a part of a tooth. the lines are where the "crushing" took place as the tooth grew. this is actual size of the "piece" we found. but it was carried by a beast of immense proportions. http://majikimaje.com/tusk.jpg that tusk was found on a beach in Kotzebue Alaska in 2004, Clyde was walking along the beach and he saw a small piece of what he thought was wood. He almost broke his foot when it kicked it hard. He reached down and grabbed it and the earth moved 10 feet away. He ran home got a shovel and dug this up. He was immediatley offered $15,000 for it. He declined, because he can make ten times that amount by "carving" on it. Mastadon Fossiled Ivory is tens of thousands of years old 15, - 25,000 years approximately or so they say. it is extremly brittle and can easily be softened by soaking it in baby oil. mineral oil, etc. the equisite patterns on the inside must be seen to be appreciated. very fine lines in a criss cross circular pattern overlapping.
