I found this "bone" on a beach in Edinburgh this weekend. I think it is a jaw bone but considering how worn down it is I am not even 100% sure it is bone. Can anyone tell me a) if it is bone b) if yes, is it a jaw bone? c) if yes, what is it from?
This does look like a jaw bone but there are also features which make it less likely. What ever it is seems to be quite worn and I would have expected any teeth to have fallen out, but there are structures that look like teeth. More photos would be helpful, perhaps from four angles, ie. the one you have and with it rotated 90 degrees, and other 90 etc. The original photo has a pencil in it but if you used a ruler we could get an accurate measurement if needed. Thank you.
