1. Describe unidirectional respiration. What evidence is there that this is likely a SAURISCHIAN feature? 2. What kinds of design constraints are associated with having an extremely long neck? 3. What evidence is there that Sauropods didn't really chew their food? How can Sauropods be herbivores but not have developed much chewing ability? 4. Why did paleontologists believe sauropods were aquatic and why do they no longer hold this view? 5. Review the evolutionary history of the sauropodomorph dinosaurs.
