Brachiosaurus is the one of many of the biggest dinosaurs in history and are used in the community as the base and movement of the firefighter truck for the fireman. They are also commonly use as a bus type of serves to transport people. (Brachs to dinotopians). This is the one of their alone means of movement of the people and supplies across Dinotopia.
Like all sauropod dinosaurs, Brachiosaurus was a quadrupedal animal with a small skull, a long neck, a large trunk with a high-ellipsoid cross section, a long, muscular tail and slender, columnar limbs. The skull had a robust, wide muzzle and thick jaw bones, with spoon–shaped teeth. As in Giraffatitan, there was an arch of bone over the snout and in front of the eyes that encircled the nasal opening, although this arch was not as large as in its relative. Large air sacs connected to the lung system were present in the neck and trunk, invading the vertebrae and ribs, greatly reducing the overall density. Unusually for a sauropod, the forelimbs were longer than the hind limbs. The humerus (upper arm bone) of Brachiosaurus was relatively lightly built for its size, measuring 2.04 meters (6.7 ft) in length in the type specimen. The femur (thigh bone) of the type specimen was only 2.03 meters (6.7 ft) long. Unlike other sauropods, Brachiosaurus appears to have been slightly sprawled at the shoulder joint, and the rib-cage was unusually deep. This led to the trunk being inclined, with the front much higher than the hips, and the neck exiting the trunk at a steep angle. Overall, this shape resembles a giraffe more than any other living animal.
