KT boundry event

I just finished Alvarez's book

"T. Rex and the Crater of Doom" the title of which is a bit misleading,
and Mr and Mrs Rex do not appear.

I am puzzled, however, by his poor argument that after the KT boundry
event the mammals were able to take over the niches (large animals)
that dinos had previously occupied. The question arises: Why didn't we
get dinos all over again? Why didn't we get large reptiles, at least?
Why large MAMMALS?
