DUUUDE that's a total hard stop - look at how good the belt looks before and fter that. It must have stopped dead. Weird, because one would have expected a sudden stop like that to be nearly impossible, and cause damage elsewhere.

Have you popped off a valve cover yet? Does the oil pump rotate freely?
So, something locked the cam(s) or oil pump and the crank tore off 7-8 teeth. 7-8 teeth normally MIGHT be survivable, although you already said this is not so with Variocam.

I can't imagine anything other than a toothed roller would have stopped the belt dead like that. The interesting thing is, as Sterling says the crank gear is good, then why would IT kill the belt there and not the oil pump (if that is the culprit) ... Actually, this way the only possibllity is the cams - they have most traction.

Looks like the belt stopped, and the crank kept going for several revolutions. I think the crank has the fewest engaged teeth, so its the weak point.
Which side is the fuzzed up part, tensioner?
