Bipedal dinosaurs probably walked with a swagger when walking, swinging their tails in the same way humans swing their arms as they walk.
The weight of a dinosaur's head has been counterbalanced by the weight of its tail, which dinosaurs used to have traditionally considered a counterbalance. The Royal Veterinary College in London's Peter Bishop and John Hutchinson believe that the tail played a more active part in a dinosaur's gait. The tail would move up and down with every step to control the dinosaur's angular momentum, and improve its walking efficiency.
This is a computer simulation.
