You do know that the dinosaurs, with their big lungs, were suckin' back
about 6.5 times (2300 ppm) the CO2 that exists today, when they were

That was 150 million years after the Mississippian Epoch for christ sakes!

and exactly how did that affect their intelligence?


Dinosaurs had intelligence? Instinct yes, and 2300 puny ppms (0.23%) of
CO2 didn't affect their instincts. They were on earth for about 175
million years. More than 50 times longer than humans.
