How did sauropod dinosaurs move?
Diamantinasaurus matildae (‘Matilda’)
Hocknull et al. 2009PLoS One
You can’t move without muscles
CT and MRI scan of saltwater crocodile Digital dissection using Mimics software
Physical dissection of crocodile

Digital data collection
What can this tell us?
• Mobility, speed and hind limb rearing
• Muscle forces – which muscles worked when during movement and how this affected the shape of ‘Matilda’s’ bones
• What kind of behaviours ‘Matilda’ regularly performed
