1. What would North America have looked like during the era that Rivers and crew visit? Does de Camp have the geographical details right?

2. What sort of plants would visitors to the Middle Cretaceous epoch encounter? How would they complicate hunting?

3. "A Gun for Dinosaur" is rich with animal life. What was the mix of animals like in the era it covers?

4. Many, probably most, experts on dinosaurs currently believe that apatosaurs lived on dry ground in large woodlands rather than in water and swamps. How accurate are de Camp's account of other dinosaurs?

5. De Camp mentions other eras besides the Middle Cretaceous that he would be willing to take his prospective clients to. Write a story of the hunt they undertake in one of these other eras. What would they hunt?

How would they survive? What difficulties would they encounter...
