Rhabdodon was probably an important herbivore in Cretaceous Europe. Rhabdodon's predators may include the potentially dubious ceratosaur Tarascosaurus, and young may have bee prey for Pyroraptor; thought adults where probably to big for either; as Tarascosaurus was around 2.5–3 m (7–10 ft), Pyroraptor around 2 m (6–7 ft), and Rhabdodon 6 m (18–20 ft).
