I do note that giant theropods tend to come from the same ecosystems as giant sauropods; rarely is this not the case. If being big allows a theropod to kill a sauropod more easily, we would expect to see giant theropods cropping up alongside smaller sauropods before seeing giant sauropods alongside giant theropods
I am sorry to go back on my word here, but this is COMPLETELY illogical.Just to be clear -- you are claiming that the association of giant these (predator) and giant thoses (prey) is actually evidence they did NOT evolve in tandem? No typo here?
Interesting...Further -- YOU might expect to see a predator evolve to a size larger than it needs to be just because the kill itself is 'easier'(thereby outracing the prey in the predator-prey relationship), but I certainly would not.
Could you clarify exactly who "we" is?
