Karinna ~ I see that you have been questioning the bones, the heat required to burn them, etc. You are not alone
We had a few threads we discussed it in early on too, I think it might be the bones one, not sure if you will find anything interesting in there or not. I remember discussing the rivets (from jeans) and how much heat would be required to burn/melt those.
Personally, I don't really question so much that they are TH's bones, I absolutely question where they were burned though. And IMO those bones were moved to that fire pit.
