If _Nanotyrannus_ is a valid taxon, it could.  Of course, most of Horner's
objections to _T. rex_ predation would actually apply to all tyrannosaurids,
so the point is moot.

If the bigass oviraptorosaur was a predator, it might concievably taken down
at least mid-sized prey (young ceratopsids, thescelosaurs, etc.).

Otherwise, any large non-_T. rex_ terrestrial predator in Lancian sediments
has slipped under our taphonomic radar, at least so far.
