Re: Mammals preying on giant azhdarchid pterosaurs!

My guess would be that he is asking why so many
species of marine reptiles suffered the same sort of
sudden termination suffered by all species of
non-avian dinosaurs, and at the same time. Mammals
may have been intrepid at getting at eggs, but not
that intrepid. Not a bad question.
To be perfectly fair to John (though I certainly do not accept his
hypothesis) the one group of Mesozoic marine reptiles known to be
live-bearing, the ichthyosaurs, apparently died out long before the end of
the Cretaceous. Of course I'm still trying to figure out how egg-eating
mammalian predators (which presumably have been around since the Triassic)
not only wiped out dinosaurs at the K-T, but ammonites, rudist corals,
