Dinosaurs have changed since I was a kid. Scientists keep discovering new things about what they looked like and how they lived. It's hard to keep up!

Bones, feathers and blood vessels not visible with the naked eye can be seen in the scans for the first time. How much will this change what we know about extinct creatures?
