l specialize in fossils I find myself in interior Alaska along the rivers. Most are 40,000 to 60,000 years old, from the last ice age. Such finds have to come off land with mineral rights. Mammoth and bison are most common but also camel, musk ox, wolf. I attend 'the' fossil show in Tucson each year, the biggest show in the world. My mother lives there and I show up to sell, buy, trade. I sometimes trade for other fossils, dinosaur material or items I cannot find in Alaska. I use all my types of material myself in my own art for knife handles and pendants so understand the artists needs. It is rare that the one who finds the material is the one selling it as well. Most of the material will have a story and 'provenance.' Since I am the source I can answer questions,, provide authenticity and have the best prices with no middle people.
