The sauropods form one of the three great dinosaur groups. The sauropod dinosaurs roamed the planet for millions of years, with creatures ranging from the smallest of the sauropods, Magyarosaurus, to the huge Brachiosaurus. This one-of-a-kind compendium covers all known sauropod species and features more than 2,000 diagrams and technical drawings alongside hundreds of full-colour reconstructions of specimens. The book is divided into sections that make it easy to navigate the amazing world of sauropods. 'Comparing Species' is organized by taxonomic group and gives comparisons of the size of species, how long ago they lived, and when they were discovered. 'Mesozoic Calendar' shows the positions of the continents at different geological time periods. 'Prehistoric Puzzle' compares bones, teeth, and feathers while 'Sauropod Life' answers questions such as what did they eat and which was the most intelligent.
