Hopefully this photo will show up better than the last. As you can see, I am new to using this and my first post did not come out well. I found this washed up on the beach in Charmouth last week. It looks like bone but feels like stone. Is around 2 inches long. This end in the photo reminds me of a mammoth tooth, but it is small, so can it be one? The other end has 4 holes. Can anyone tell me what it is?
