I won't speak for the hadrosaurids (although I buy them as Kritosaurus!),
but all recent work on tyrannosaurids includes Maleevosaurus as a juvenile
Tarbosaurus. The Saurophaganax situation has less agreement: some (e.g.,
Smith) consider it as A. maximus; others as a distinct taxon.  I can say
that the most complete description of this taxon is in press, so folks
should wait for the paper.  (Wow, it's been awhile since I wrote that!)
