Daniel Eskridge/ShutterstockWhen all we have left of dinosaurs is their fossilised bones, how do we know what they looked like on the outside? That’s what nine-year-old Kara from London wanted to know. She joins our host Eloise and paleobiologist Neil Gostling on The Conversation’s Curious Kids podcast to find out all the ways scientists work out what dinosaurs looked like – from the way they walked, to their muscles and even what colour they were. In each episode of The Conversation’s Curious Kids, a child joins host Eloise to ask a top researcher their burning question.
