Could dinosaurs wag their tails?

Computer simulations of dinosaurs has yielded an accidental discovery, their tails wagged when they walked. Historically it has been accepted that the giant creatures' tails were a counterbalance, helping to keep them steady. Studying locomotion in fossils has always been tricky, but a research team at the Royal Veterinary College in London has found dinosaurs' tails actually moved and helped them to walk efficiently. Dr Peter Bishop, who is currently a research fellow at Harvard University, says high tech simulations have revealed their tails could actually swing up and down Photo: Peter Bishop
