Re: Mammals preying on giant azhdarchid pterosaurs!

Exactly.  Nature develops checks and balances.  Egg-eaters can only eat so many
eggs and so many kinds of eggs (because of behavioral and physiological
complications).  The only time I've heard of egg-eaters destroying species, was
on the islands where snakes, cats, and rats were introduced by humans.  Those
new animals were sudden additions; if they had evolved on the islands, the prey
would have evolved behaviors to get away from their predators.
