hi everyone :)

a friend of mine has found this jawbone, it doesn’t look like anything that any of us has ever seen before and we were wondering how to get it identified?

the penny is a reference for size. i hope the image is not to large, but i wanted to make sure there was enough detail

anybody know what kind of creature it may have come from, or a link to a site/person that would be able to help
