The leg of Argentinosaurus

To estimate the gait and speed of Argentinosaurus, the study performed a musculoskeletal analysis combined with computer simulations. Similar analyses have previously been conducted on hominids, terror birds, and other dinosaurs. To conduct the analysis, the team had to create a digital skeleton of the animal in question, estimate the muscles and their properties, and estimate the weight and how it's distributed. Then using computer simulation and genetic algorithms, which could be optimised for metabolic energy cost or speed, the digital Argentinosaurus learns to walk. The study estimated that their 83 tonne sauropod model was mechanically competent at a top speed of 2 m/s (5 mph) but was approaching a functional limit
