I would say it was a mixed bag.
T. rex strikes me as being a fairly general large carnivore,
perhaps specialized for large prey and ambush hunting. However,
the decrease in aridity across the K-T boundary would have *increased*
cover, and thus increased the availability of ambush sites. (Of
course the disappearance of all the large prey animals may have had
the opposite effect)
As to the herbivores, _Edmontosaurus_ was a fairly generalized
browsing herbivore, while _Triceratops_ may have been a specialized
browser of some sort. And _Thescelosaurus_ was certainly a fair
Ornithomimids may have been generalist small vertebrate feeders.
The peace of God be with you.
