This is a 40 page study guide that discusses dinosaurs ranging from Brachyosaurid to Ceratopsian. It also includes questions that you can fill out yourself in order to fully grasp your understanding of the content. After studying this, you should never question yourself on whether or not you understand a saurischian/ornithischian dino! I have met with the professor every week for a month as well as worked on this study guide for a month. The professor has read the entire study guide and said th...
