1. as you say, _near_ extinction
2. goose are rather defenseless
3. foxes are bigger than any Mesozoic mammal AFAIK (save perhaps
*Kollikodon*)
4. I'd like to see a fox capable of stealing an egg under the nose of a
*Saurornitholestes* or *Troodon* (and surviving that)

Indeed. But to argue that it represents catastrophic extinction, when we
have evidence of a catastrophe at the same time, is _logical_ (parsimonious
and whatnot).
