The Brontosaurus was by far the biggest Dino-Rider toy made and for that matter, one of the biggest toys ever made, dinosaur. It retailed for $80 and was about 3 feet long. Despite its huge size, it was highly detailed and well made. The Brontosaurs included 3 miniature Rhamphorynchus dinosaurs that served as aerial bombers. It also had a crane with 3 different attachments and a land mine chute. The head and neck of the Brontosaurus could be moved up and down. In an effort to keep costs down and make the Brontosaurus (somewhat) affordable, Tyco apparently had to scrap a number of features that it had originally planned, including an entirely different weapons scheme, motorized walking action and 4 figures instead of 3. Check out the "MUSEUM" section to find out more about the alternatives that were planned.
