This study of the habits of dinosaurs covers how they ate, how they reproduced and how they moved. Robert Bakker's illustrations are based on first-hand studies of dinosaur exhibits in museums throughout the world. This book supports the view that dinosaurs were warm-blooded, intelligent and agile creatures bearing little resemblance to existing reptiles. More than 12 years ago, Robert Bakker provoked a heated controversy on this subject, opposing the widely held belief that dinosaurs were cold-blooded, lumbering and of low intelligence.
