     That may have been inevitable.  If a diplodocid reared up and ate 
everything it could reach, how long before it stripped the tree of 
all the foliage at that exact height?  It would have to drop down again 
and move to a new tree before very long.

     Those thumb claws were not that large, even relative to the size of 
an allosaur, and don't looke especially sharp to me.  The crush factor 
would be pretty significant, but I don't see diplodocids or dicraeosaurs 
"impaling" anything.
