Cannibal Jack Headgear - Don't know what I made...?

[Capn_Jack_Savvy]

It was there in the photo so I had to make it! Actually it appears to be some sort of animal vertebrae, dried out ears (yummy), a tooth attached to a chain, and some sort of dried out leg! Personally I think the prop dept just looked around and found things lying around and through them together!!!
