Microscopic bone analysis of therapods indicate they were warm blooded and had feathers.

This I have to hear! Please tell us how they found out from bones that dinosaurs were warm blooded!

The bones of warm-blooded animals have more passages for blood vessels than those of cold-blooded critters. Therapod dinosaur bones have lots of passages for blood vessels (like birds or mammals) when compared to turtle or lizard bones, which have fewer passages for blood vessels.
