    Absolute brain size is poorly correlative with intelligence. Brain size relative to body mass is better.

    Larger animals need larger brains mostly to operate their large bodies.

    Dinosaurs and other non-mammalian giants managed to go small.

    But large dinoasaurs still had larger brains than small dinosaurs.

    But I was not comparing dinos to other dinos.

    What was the point you were trying to make then? The point you were arguing about is that larger animals tend to have large brains to operate their large bodies. Are you disputing that?

    Yes, since large animals 65 MY ago were often larger than existing large animals, and had small brains. Meaning species and descent is a more important determiner of brain size than just body size.

    1] Large dinos back then apparently had a nerve center near their hips that helped operate their hind quarters. Not actually sure if there's any truth to that.

    2] I never intended to suggest it was a universal rule, and one that applied across dozens of millions of years.

    Generally, large animals have large brains. But they don't have correspondingly high intelligences to match.

    Well, now, that's a counter-assertion, and you'll have to defend it.

    I see what you meant now. Actually, I didn't understand when you wrote:

    When you wrote "go small" I thought you were talking about body size, but now I see you meant brain size.

    Just so everyone is clear... no he doesn't. This is OTB, not ATM nor CT; ATM and CT are the only sub-forums where there is any requirement to defend assertions. It would be nice if people did so, but there is no requirement, nor can it be demanded.

    Brain size isn't the important factor though is it...it is number of neurons etc and level of connections and how they are connected. Perhaps if a cow species evolved to be twice as high then maybe its brain would become eight times the size, but with not much other difference in composition.
