The Rise and Fall of the Dinosaurs

I struggled to get into this one even though my paleontologist friend really liked it and recommended it to me. About one third of it was really interesting and informative. The next third was repetitive. How many times do you actually need to say what Pachycephalosaurus means? The last third just felt like name dropping. Maybe if I was more involved in paleontology it would matter to me, but it didn't.
