"Woolly Mammoth Tusks, are from Pleistocene 'Ice Age' deposits and are organic fossils due to their frozen preservation for at least 10,000 years.  Searching the freshly eroded permafrost on rivers, cutbanks, gravel bars, and within the water itself will yield specimens and broken examples.  Woolly Mammoth ivory is the only remaining legal ivory in the world.  With the correct perceptions in government and the private sector, this ivory is abundant enough in Siberia, Alaska, and the Yukon Canada to 'substitute' all the major ivory producing species in the world."
