How do you walk if you weigh 80 tonnes?

Scientists from the University of Manchester have created a "digital robot" of the biggest dinosaur ever to have walked the Earth - Argentinosaurus.
This animated sauropod has shown the researchers how these creatures would have walked, showing that supporting their 80 tonne weight would have stretched muscle and bone to the limits of its capabilities.
The team used a laser scan of the dinosaur's skeleton and mapped onto that its tendons and bones.
