That looks more like the camshaft stopped dead and everything between it and the chain was stripped to hell as the chain kept spinning. I don't think those tensioners failed, I think they did their duty to the bitter end.
The locking washer thing that's chewed to hell is what actually holds the sprocket to the cam, and the threads on the big cam nut also look pretty shiny...
Edit: As for getting it out. If it were me (and I can only judge by the pictures) I think I'd try rocking the camshaft back and forth a bit while alternating with light taps at that jammed nut with a hammer and punch. It got jammed in there in one direction--maybe in the other direction it'll loosen up.
