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 in the US - tells Nine to Noon's Kathryn Ryan high tech simulations revealed their tails could actually swing up and down.
