This is not the original skeleton, which is preserved in London's natural history museum, but a replica which one of the guides told us was called Bob by the staff as when the cave floods his skull sometimes comes off and bobs about.
The guide incidentally was called Dan, was absolutely lovely, and really wants Cheddar Gorge to start running DnD games in the cave but the management isn't going for it. I think that would be an amazing idea and every nerd I know would be beating a path to their, uh, cavemouth. I'd be surprised if anyone following me is part of Longleat Management, but I've seen weirder things happen on here so if you are please make this happen
