World-renowned dinosaur illustrator and researcher Gregory Paul provides comprehensive visual and textual coverage of the great Mesozoic animals that gave rise to the living dinosaurs, the birds. Incorporating the new discoveries and research that are radically transforming what we know about dinosaurs, this book is distinguished both by its scientific accuracy and the quality and quantity of its illustrations. It presents thorough descriptions of more than 735 dinosaur species and features more than 600 color and black-and-white images, including unique skeletal drawings, life studies, and scenic views--illustrations that depict the full range of dinosaurs, from small, feathered creatures to whale-sized supersauropods.Heavily illustrated species accounts of the major dinosaur groups are preceded by an extensive introduction that covers dinosaur history and biology, the extinction of nonavian dinosaurs, the origin of birds, and the history of dinosaur paleontology--and that also gives a taste of what it might be like to travel back to the time of the dinosaurs.The Princeton Field Guide to Dinosaurs is a must-have for anyone who loves dinosaurs, from the amateur enthusiast to the professional paleontologist.The first authoritative field guide to dinosaursCovers more than 735 speciesBeautiful, large-format volumeLavishly illustrated throughout, with more than 600 color and black-and-white drawings and figures, including: More than 130 color life studies, including scenic views Close to 450 skeletal, skull, head, and muscle drawings 8 color paleo-distribution maps Color timelineDescribes anatomy, physiology, locomotion, reproduction, and growth of dinosaurs, as well as the origin of birds and the extinction of nonavian dinosaurs

    Through overfishing, climate change, and ocean pollution we are disrupting the creative procreation that drives the wild abundance of life in the ocean. With wit and scientific rigor, Hardt introduces us to the researchers and innovators who study the wet and wild sex lives of ocean life and offer solutions that promote rather than prevent, successful sex in the sea. Part science, part erotica, Sex in the Sea discusses how we can shift from a prophylactic to a more propagative force for life in the ocean.
