Yes, I should have said North American allosauroids.  The only North American 
allosauroid that I can think of off of the top of my head that has been 
reconstructed to possibly approach T. rex size was Epanterias, but that is 
still very questionable.  

What was the approximate age of Saurophaganax, and has anyone looked at its 
possible prey?  Judging from its discovery in the Morrison Formation, we can 
all make some very educated guesses, but has any herbivore material been found 
at the Saurophaganax site?
