As I recall, the extinction *did* take out all of the large vertebrates, and
a whole lot of the smaller species... but not all of them, and some of the
smaller species, such as our long-gone ancestor Purgatorius (which may or
may not be quite that old, but is at least Paleocene) and tons of other
small mammals, may have had sufficient niches open up as allow evolution
into larger descendant species.

At least that's how I've been lead to understand it, corrections are quite
welcome.
