019 - Chapter 18 - How Pterodactyles may have originated

In the 19th century, Sir Richard Owen introduced the term dinosaur, meaning Terrible Reptile or Fearfully Great Reptile. This sparked a fascination for Harry G. Seeley, a law student who attended a lecture on flying reptiles, ultimately leading him to dedicate his life to paleontology. Seeley classified dinosaurs into two distinct groups lizard-hipped and bird-hipped. He also revolutionized the understanding of flying dinosaurs, presenting them as warm-blooded, active flyers rather than cold-blooded, passive gliders. His acclaimed book, Dragons of the Air, serves as an in-depth exploration of the anatomy, classification, and evolutionary origins of Pterosaurs, shedding light on their intriguing relationship with birds. - Summary by Jeffery Smith
