  1. Based on examinations of the pelvis and leg bones of the Tyrannosaurus rex, paleontologists believe that it moved with its body parallel to the ground. The T. rex probably kept its long tail high in the air to counterbalance the heavy weight of its head. Markings on the bones indicate that the dinosaur's leg muscles were very strong (enabling it to run quickly), and that its relatively short arms were strong enough to bear about 400 pounds (180 kilograms) of weight.
