I'd guess coyote teeth. I had some and made a necklace with trade beads and brass beads. Got a lot of comments on it and ended up making some up as gifts for friends and family. My mom wears hers all the time!
Without knowing the length or width, its hard to determine the species, but these appear to be canine teeth from either a canine or cat. I have two such teeth from two of my cats that came out after they took bad falls and broke the teeth off on furniture and shelf edges.
Everybody was pretty close, hard to tell without something for scale. Red Fox teeth, found a skull while turkey hunting last week and yanked them out. I think I'm leaning toward using them as inlayed teeth on a snake head war club a friend gave me to work on. :grin:
