Daspletosaurus?



Say, what is the currently accepted relationship of Daspletosaurus?
Seperate genus?  Subgenus of Tyrannosaurus?  Or, instead, subgenus of
Albertosaurus?  How many species in the genus?  Just *torosus*?  And--is it
possible that Trannosaurus itself became larger because of the seeming
shift in the duckbill/ceratopsian ratio, and the resultant need to go after
more dangerous prey?
