Here we go again with what these animals could not do. Again, they were
extremely successful creatures which evolved over long periods of time.
If they could not deal with the environment they either a)would not have
survived, which of course they did, b) developed features which let them
deal with this environment, or c)migrated to an area where they could
survive. I could not imagine Sauropods living in an environment they
were not capable of survival in , therefore the terrain in these areas
could not have posed that much of a threat.

How did my previous post turn into this turkey thread?! Between that
and the cows we have the barnyard list. Dinotipping!:-) I do like that.
