unfortunatly i do not have a picture of it as its at my parents house. But his thing has baffle me for the past 15 yrs!!!! I have however seen something similar at a museum in somerset and i believe it may be an iron age oxe, It was half a jaw bone, with what looked like two sets of teeth running down the side. It had a large crater at the front which had a large tooth like thing in it, which unfortunatly fell out when i picked up. After a lot of searching i could not find it but I can remember it was blunt and brown in colour. As to location, i found it in the forest at exmoor and thats as much as i can remember. I know this is not a great desciption but does anyone have any ideas?
