While it is generally true that lions do not follow the herds(ie, 
mostly true), there are some prides and individuals that do follow 
the zebra and wildebeest herds as they migrate.  As has been pointed 
out many times on this list, that doesn't necessarily correlate with 
dinosaur predator behavior, but it is interesting.  There are not 
enough of these predators to have a significant effect on prey 
population however.  This is in contrast to the territorial lions 
prey encounter as they migrate.

Is there a consensus on the average temperature of "alaska" in the 
very late Cretaceous as well as the minimum?  I have seem several 
ranges.  Since it is clear that there were nesting hadrosaurs towards 
the Arctic Circle, I'd like to have a clearer understanding of the 
temps there.
