And we are claiming that this is an invalid challenge.
Such a restriction to terrestrial only is artificial and useless.

I think he comes very close.

The same thing that killed everything else that died at that time.
How hard a particular group was hit was effectively random, except for
those few groups such as frogs that were immune to whatever the cause
By the way, regarding the 25% extinction in crocodilians:
were any of the terrestrial crocodilians still around
at the end of the Cretaceous?
The peace of God be with you.
