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
