I would just like to throw in a couple things on this. Just imagine
putting say Isaac Newton's brain in a dinosaur. Would that really be
beneficial? He would be daydreaming about something and get snuck
up on and get munched. For a dinosaur, the only intelligence you need
to be effective is to be good at catching prey, humping mates,
protecting offspring, the basics. They didn't have hands either.
Hands were a really big one. With no hands a big brain is so much
less effective. Not much to DO without hands. Limited options
compared to us
Besides, most creatures are so BUSY doing the basics. I think
humans aquired free time in groups, and you know what they say about
idle hands!
I bet there were fairly smart dinosaurs. Not like our kind of
smart, just sneaky, observant, perhaps pack cooperation. They were
smart at what they did. They had no use for calculus. We got a
different kind of smart. Abstract thought. Not very useful for most
creatures.
A better question might be "why didn't chimps evolve along with
us?" I don't know. (I don't "know" any of this by the way, just
spewing my thoughts)
