Were Dinosaurs Cold-Blooded Or Warm-Blooded?

Scientists still haven’t settled the hot debate over whether dinosaurs were warm-blooded like birds and mammals or cold blooded like reptiles, fish and amphibians.

And some research suggests that dinos may be somewhere in between.

A new video (above) from the YouTube series SciShow explains that an analysis of dinosaur bones may prove that dinosaurs were mesotherms, not quite hot-blooded and not quite cold-blooded either. The mesothermy theory may help explain how the giant prehistoric creatures could have stayed active in cold weather — when cold-blooded animals could not have — and conserve energy when needed.

Are there any mesotherms alive today? The great white shark, tuna, and echidnas are just some of the middle-blooded creatures that are still thriving.
