The Princeton Field Guide to Sauropod and Prosauropod Dinosaurs by Gregory S. Paul (Hardcover)

"A field guide to the herbivorous dinosaurs of the Late Triassic, Jurassic, and Cretaceous. Prosauropods were ancestral species to the sauropods, and date from the Late Triassic to Early Jurassic. They comprise four families: Platesauride, Anchisauridae, Massospindylidae, and Melanorosauridae. Some prosauropod species were able to walk on two feet, while the later sauropods were all quadrupeds. Much more recognizable for most people, sauropods included iconic herbivorous dinosaurs such as the massive brachiosaurs, stegosaurus, Triceratops, and so forth. The text includes a synthesis of recent taxonomic re-evaluations and scientific discoveries, as well as skeletal reconstructions, muscle studies, and a wide range of color drawings of individual species and scenes from the world of dinosaurs"--
