The Ornithopods include Iguanodon, one of the first dinosaurs ever discovered and analyzed, and perhaps the best-documented group, the hadrosaurs or 'duckbilled dinosaurs.' The Ceratopsians include Triceratops, known for its distinctive three-horned skull and protective collar. This book collects information on these two groups of animals.
