Question: How do you record dinosaur motions?

@Keisha Lynch We’d really like to go back in time and film dinosaurs to make a natural history documentary, but we cannot (yet!). So we collect the bones and create copies inside the computer. We know how they fit together (like a jigsaw puzzle) and we can see how big the muscles were (there are dents in the bones where the muscles join them). We put all this information into a computer program that uses maths to work out how all the bones moved together to help the dinosaur walk.
