She is at her happiest out in the field, with a hammer and a notebook, studying rocks and looking for dinosaur remains. We tend to lump dinosaurs together as though they all roamed the earth at the same time which is silly - given that they had the run of the place for nearly two hundred million years. Susie wants to sort out exactly which dinosaurs lived when. Although she warns, the fossil record is woefully incomplete. We will probably only ever know about 1% of what there is to know about all the dinosaurs that ever lived.
