I keep re-discovering entelodonts AKA "Hell Pigs", a pig-like apex predator that went extinct about 16 million years ago.

Okay, I googled.

It seems to me cetaceans had an alarming land-dwelling predator in their lineage but darned if I can find it.

Andrewsarchus has teeth similar to those of early whales, IIRC, though I'm not at all sure where it fits in the family tree.

Or maybe this critter: http://www.hmnh.org/archives/2009/02/04/maiacetus-innus/ ?

But if you go back far enough, they aren't very alarming at all:
