"Bagualosaurus" probably had a fully herbivourus diet. The fact that the "Bagualosaurus" already has a dentition well adapted to the consumption of vegetation is especially important for the evolutionary history of the dinosaurs. Pretto explains that all sauropods have two characteristics in common: gigantism and herbivorism. "Bagualosaurus" and other early sauropodomorphs may have adopted the leaf diet, which may have been the source of sauropod gigantism.
