Like other reviewers, I too was fascinated by dinosaurs as a child, and remain so as an adult. The Hot Blooded Dinosaurs was one of my favorite books growing up. Mr. Desmond brings history, physiology and other sciences together in an easy to understand book, challenging the old idea that dinosaurs were slow, dull creatures. As a student of Biology, I remember questioning why Sauropods would drag their huge tails on the ground (ouch). And the therapods were definitely built for speed. Why would animals built for an active life be labeled as ectothermic? The Hot Blooded Dinosaurs builds an interesting case by looking at these specialized animals in a new light. Follow The Hot Blooded Dinosaurs with The Dinosaur Heresies by Robert Bakker, Ph.D. Your middle school student will like The Hot Blooded Dinosaurs as much as an adult. I purchased this book in hard cover as my original is literally in tatters from years of reading. Can't wait for it to be delivered so I can re-read an old favorite.
