This bone might not like a mystery at all if you know a bit about bones. But there are two big mysteries: what animal is it from, and how did it get there ?
Dad found it two weeks ago when walking in Suicides Graves wood. It was in the south-west corner, maybe quarter a mile away from where I found the red deer calf bones, and it was well inside the wood itself, away from the fields. It is easy to see it is either a metatarsal or metacarpal (which is a lower leg bone) from an animal like a sheep or deer but that doesn't solve the mystery.
