What specific herbivores are inferred to have roamed the Late Cretaceous environment of Xenotarsosaurus?

Answer

Sauropods and ornithischians

Based on the environmental context of its Late Cretaceous Argentinian habitat, it is reasonable to infer that Xenotarsosaurus fed upon the herbivores roaming that environment. The text specifically names sauropods, such as the large titanosaurs common in Cretaceous South America, and ornithischians as the types of plant-eaters that would have constituted the available prey base, either alive or as carrion.
