Bigger dinosaurs had warmer blood.

The bigger a dinosaur was, the warmer its blood, a study of the big beasts' fossil remains shows.
[...]
But as dinosaurs got bigger, they became less efficient at dissipating heat and this helped to keep them warm anyway. This is known as inertial homeothermy.
According to the scientists' equation, the enormous sauropod Apatosaurus - which at 13,000kg was among one of the biggest dinosaurs - had a body temperature of just over 40C.

And the first thing that came to mind for me was how DID they shed heat?

If they had to move fast to escape a predator, that would have raised their temperature even more...
