I find a lot of Drilled Teeth, including Bear Teeth, and to me it looks a small Bears Tooth from a young Bear. I have a couple smaller Bears Teeth. The bigger Teeth in the first and last pictures are both over 3 inches long and are Bear Teeth. The 5 larger ones in the second picture are all Bears Teeth and are from 2 to 3 inches longs. All the rest of the Teeth are Coyote, Wolf, Dog, Fox, etc.
