Could dinosaurs wag their tails? - a podcast by RNZ

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
