I think what he's saying is that crocs know not to eat little hippos because
big hippos kill the ones who try.

So what are you saying? That the duckbill authorities would go after any
crocs who ate duckbills? Why don't you jump in a cage with a dangerous
predator and see if it considers you food? Predators often avoid humans
because humans are also dangerous, and there is usually easier prey.
To a Mesozoic croc, a hadrosaur would look like pretty easy prey.

Steve, you are the ONLY person here who seems to think that hadrosaurs
were "smart enough" to avoid being croc food. They didn't survive by avoiding
predation; they survived by being prolific breeders. This is the way of most
relatively defenseless herbivores.
>Past scares with hippos might also encourage crocs to behave.
That was Ed Traxler's point. But hadrosaurs didn't bite adult crocs in half.
PLEASE don't compare them.

Steve, give it up! Hadrosaurs WERE NOT A THREAT TO CROCS. Sure, maybe
one stepped on a croc now and then, but that simply means that it didn't see it
in the first place. Remember who's the predator, and who's the prey!
Now, can we give it a rest?
