The object is very hard and the end shown in the last picture is worn smooth. I looks a bit like a tooth of some sort such as from a hurbuvor such as a mamoth but I dont know anything about such things.
Thats a good shout, not quite as exciting as I had hoped but I will have a look at images on the web and see how they compare. Is there any easy way of getting an approximate date of the tooth?
Sorry Martin I'm not that good at animal remains I just come across them by accident now and again Butterflies and Clay pipes which is not much help to you is my main interest
What will help others is the location of your find
