How an animal moves can tell scientists a lot about how it lives. That is how researchers hope to learn more about an ancient crocodile-like creature called Orobates pabsti. Orobates lived before the dinosaurs. It is known as a ‘stem amniote’ — an early offshoot of the lineage that led to ‘amniotes’, namely birds reptiles and mammals. Using 3D scans of an exquisitely preserved Orobates fossil and an associated set of fossilised footprints, researchers built a dynamic simulation. The simulation also incorporates data from extant animals such as lizards and salamanders to constrain the movement. The researchers then tested their simulations in the real world using a scale-sized robot. Bringing Orobates back to life.
