Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought they were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.

The idea of warm blooded reptiles is nothing new. I heard about this close to 30 years ago. But now they have some proof to that fact. I find that really interesting. The big mystery to me is how some of them go so big without being crushed under their own weight or sinking into the ground. It is as if the gravity was not as strong back then or something?
