Goodwin studies how dinosaur bones change with growth and how fossil bone is preserved, i.e. what's the difference chemically and mineralogically between an unaltered modern and fossil bone? What is the effect, if any, of the burial environment on the mineral and chemical properties and how do you measure it? Mark also has research interests in the behavior and life history of pachycephalosaurs, or dome-headed dinosaurs, and more recently with the very well known three-horned dinosaur, Triceratops. Field work in California, Montana, Alaska, Israel, and Ethiopia, has provided many new fossils to work on.
